TBM 5879 SG demo
« on: February 03, 2014, 09:24:25 am »
Here's a short clip of the new TBM 5879, as it currently resides on the breadboard....
I just bought a TASCAM DR-05 to use for this purpose and, if nothing else, I'd like to hear your opinions of the sound quality,,,,and if this will be an acceptable way to demo different amp circuits, for the future.

I decided to just hit record and live with it and here you go....I think it's an OK example of how the amp sounds, but I am looking forward to redoing it with my Les Paul.

This was done with the recorder sitting on a stool about 3 feet from the speaker, and about 1 foot from the boombox that was playing the backing track.
Warmoth parts-o-caster, Seymour Duncan JB bridge pickup with the volume rolled back to about 7.

My personal favorite moment comes between 1:00---1:14 where I get that nice little controlled feedback thing happening  :icon_biggrin:

It was 52 degrees in the shop, so I would like to blame some of my slop on cold hands,,,,but back in the day, man, I could play Eruption outside in a blizzard with 50 mph winds, so some of it is just a result of old age.......I'm 45!  :embarrassed:

I think the lead tones sound great, love the sustain. How do chords sound with those settings?

Thanks Punk,
I think the chords sound good too, and should have taken a minute to record part of a clip of just rhythm playing.......any requests?  :wink:
I think the 5879 adds a touch of clarity and separation to the notes, so even though I'm driving it pretty hard, it doesn't "mush out"
I like it for a nice punchy pushed ZZ Top kinda thing.
I rushed through this cause I had limited time, and really just wanted to confirm that I would be keeping the new piece of gear.....it was cheap enough (on sale $69.99), but if it doesn't sound good it will be going back.

I'll put that on the list for my next little recording session, and try to get a couple clips of the clean as well.
It might be tonight because I am at work getting snowed in.....again  :cussing:

Sounds great.  Sort of a Gary Moore tone.  I'll bet with a Les Paul it would nail it.  Was your volume loud, or did you get this tone at a fairly small club level?

Quit making excuses, you can play.  You may not be at the top of your past potential, but I'll bet you were not fixing toilets when you were playing eruption.

Thanks Ed,
I'll bet with a Les Paul it would nail it.....yeah, I'm looking forward to some more takes  :icon_biggrin:

The volume was very bearable, and partially because of the 6K6's and PI dampening move (see below)
The amp sounded better with the master on 8, but I chose 6 so as not to overload the input of the recorder.

I think my least favorite quality in the tone came from the speaker I chose (G12-30H)....I'm gonna put a V30 in another cab and go heads up next time.
Maybe wind up mixing them in one 2x12 eventually.  :dontknow:

I copied this over from the original thread, so you won't have to search for it:
http://www.el34world.com/Forum/index.php?topic=16447.50

I listened to the clip a couple of times and realized that I should explain a couple things....

- 5879 is switched in the whole time, no cathode bypass cap, trim pot cranked to 8
- bootstrapped cathode follower 12AT7
- Input volume on 5, treble 6, mid 7, bass 5, mid-boost switched on
- 10K shared cathode resistor in the PI, used as a power dampener, per sluckey's scrapbook (18 watt switchable power dampener)
- 12AT7 phase inverter tube
- 6K6GT power tubes installed with "master" vol. set on 6.....pretty bearable volume, sitting right in front of it
- Celestion G12H-30 in the open back, top half of one of my 2x12 cabinets

- Parallel FX mod with Mix pot on 3, and slight delay in loop....carried over from this thread:

Yea, what I mean is we did not have the same responsibilities to interfere with playing.  Actually I am a better player today than I was in my youth.  Not as fast and warmup takes longer, but I have a better ear.

I agree with the demo idea of just playing the amp live.  I really like what sleepless did with his new build and that is what I plan to start doing.

Backing tracks are cool if they do not overpower the amp, but still there are tonal conflicts.  I am really disappointed with my amp recordings.  They sound great, but that is not the point.  Live and learn.

What do you think of what the DR-05 picked up by just laying it there between the 2 sources?

I purposefully "mixed" the guitar louder than the backing track (by placing it closer to the boombox  :laugh:) so it could serve as a useful demo of the amp.

To me the tone sounds a little boxy,,,but I think that is accurate to what I'm hearing in the room, and more a result of the things I did to soften the volume,,,,,,plus the speaker seems a little harsh to me.
I am now curious to hear what it would sound like with the 6V6's back in there, PI biased normally, and V30 speaker.....guess I'll find out soon  :icon_biggrin:
I'll just have to get a longer cord, so I can stand out in the hall!

Hey man,  VERY well done!  Nice playing. I enjoyed it alot.

Amp sounds great to me. Sweet tone and sustain.

I think there are probably better speaker choices that might sound a little smoother?

Thanks man.....that was my best Tubenit impression  :icon_biggrin:.....or at least what I thought you might want to hear me play  :undecided:

I work in a big building, and my brother (10 yrs. older) works on the other side, about 100 ft away, but with multiple walls in between,,,,and at one point he came over while I was recording, and just gave me this look.....and I said:
"I'm not trying to make good music  :icon_biggrin:,,,,just show some guy what his amp sounds like".....he gave me a thumbs up and walked away, so I musta been doin OK   :dontknow:


I think there are probably better speaker choices that might sound a little smoother?
I agree 100%.
I only have a Vintage 30 and a Greenback still to try, so I'll try to get fairly accurate, similar clips of those....

Thanks for the kind words and support.......this is fun, and once I got past the embarrassment of posting what I feel is "not my best work",,,I realized that it doesn't matter, cause I'm just demoing an amp.

I think one way to get it sounding better is if I used a TELE!

SO, because of the snow,,,I packed up work a little early today and wired up my other 2x12 cab with the Vintage 30 and HATED it...

As soon as I plugged it in and turned it on, it made my skin crawl with this amp.....no good...

Nasally, sharp, harsh.....just not a good fit for this amp...

I'm not even gonna record anything because it's just THAT bad. IMHO.

So for anyone keeping score- G12H-30 = BETTER THAN > V30----for this amp
Back to the drawing board.....looking forward to trying the Greenback,,,and ANYTHING else  :BangHead:

And I was all ready to say some nice things - then you had to ruin it....

About half way through, I wish you would have switched to the neck PUP.  That would tell me more about the tone.  I think for the bridge PUP it sounded really good.  I have a feeling the neck PUP would sound nice and woody as the tone seems really transparent.  I was going to say, "Nice chops!" - but I take it back.

Looking forward to hearing more from you YOUNG MAN!

I've gone back to listen to your clip a few more times.  I really like it ALOT!   I may try the bootstrapped CF idea again after listening to
your clip.  I liked the tone when I tried it but couldn't figure out a way to balance a clean and OD that way.

I'm like Jim in that I'd love to hear the neck pickup also. 

Good stuff!   Please post more clips of your amps in the future too.

with respect, Tubenit

You just did,,,and you can't take it back
Even though I know it goes against every fiber of your being, I'll take that as a positive  :icon_biggrin:

This guitar just sits around my shop and it's kinda my "scrapper"....the single coil in the neck spot wasn't doin it for me,,,kinda sounded like one of those crappy strats....so I stuck to what was working for me  :wink:

I hate to say it but I agree completely with you, and can't wait to redo the clip with my LesPaul...a real guitar  :undecided:

Thanks for saying something...I got a little nervous there when you stopped by and didn't comment.....that's worse than your normal verbal abuse.
 :grin:
Sincerely,
LC

SG
Sounds great love the OD tone
Yes please a neck segment clip and some more with the bridge and roll the vol up and back down in increments to give us some more flavor.
Besides you need to put that new Tascam to work that sounded very good also.
I here there is still more winter to come in Philly so you will have an opportunity to go play eruption in the snow with cold hands and we will have a chance to hear how well the Tascam works out there also.   :icon_biggrin:

Thanks again T,
It really means A LOT to me that you took the time to stop back and post another really positive comment.

I do a lot of joking around on this site, and I do a lot of sucking up to people that I truly respect and admire.
YOU are a big reason why I have pushed myself to this point, and continue to push myself to find what I have always been looking for.

It took a lot for me to drop my bad habit of over-editing myself, and just post a clip that wouldn't have made it through quality control in the past.....I know that I need to get over the fact that I have a hard time appreciating my own playing,,,and just post more clips.

I'm hoping to just push myself past my self doubt and just post clips that demonstrate the amps that I spend so much time perfecting.
The kind words that have come from everyone here fuel my fire to continue tweaking, playing, recording, and sharing.
As sappy as this all sounds,,,I'm not gonna edit it!
I have found that the things I regret most in life are the things I didn't say

I liked the tone when I tried it but couldn't figure out a way to balance a clean and OD that way.
I have the same problem, but as with my other projects, I refuse to compromise the OD tone to benefit the clean tone...
I have only spent time tweaking the OD tone,,,and I see even more areas to explore with this circuit before I move on.
I'll see you back over on the build thread, and we will push forward on this.......I thought I liked the cath. bypass cap on the 5879, but I found a more interesting tone (to me) by increasing the TRIM and OD volume controls, and then reducing the gain in the PI....more to come!

I'll do that and try to enjoy all of my snowed-in time,,,,before golf season rolls back around...

I'll also have a little more time this month because of the NHL's Olympic break.....I usually catch a lot of Flyer's games

Next up....same settings with LesPaul through BOTH pickups

http://www.funnyordie.com/videos/f02d0b8cca/word-association-from-nino

I plugged the Les Paul in last night but didn't record anything because I spent a 1/2 hour just trying to keep it in tune..
Seems that my scrapper guitar that sits around the shop in freezing weather has a much greater temperature tolerance than my pampered '93 that lays around in a pink fur-lined, brown leather case and doesn't see temperature variations greater then 68-72 deg. F
In my 52 degree shop it went sharper than a 4 day old roast pork sandwich with broccoli rabe  :icon_biggrin:...

....and I had other items on the agenda

How can you tune a G string to "perfect" G, set the guitar down for 3 seconds, come back and it's a 1/4 step sharp......10 times  :BangHead:
Stretch, tune, stretch, tune,,,,punch myself in the face..........now I remember why I liked the Parker (it wasn't for the tone)

Funny, after owning several "fake" Les Pauls back in the 70's, I made a few trades and got a REAL sunburst with silver hardware.  If you looked at it wrong it went out of tune, it was ridiculous.  I was just about over my Jimmy Page/Led Zep obsession (thank goodness), and immediately traded it back in for a Strat.  I owned a couple of Jr's back in the early 70's (when they were $100-$125) and you could leave them out in the rain, drop them numerous times, and you could NOT make them go out of tune.  I know EXACTLY what you are talking about.  It is so frustrating.

Sounds to me like someone does not know how to setup a Gibson.  I have 3, 2 Pauls and a 335.  All stay in tune very well.  Bone nut and a little chapstick in the nut.  Keep in mind any guitar will change some as it acclimates to a new temp.  Mind you, they all have nice grovers on them and I also push down on the string behind the bridge, but before the stop bar and pull up to tune.  This insures the string is moving across the bridge.

I also have a Heritage LP and it always stays in tune.  I have heard this complaint many times, but usually from someone who prefers a Strat.  And it you like Jimi's live work, you don't care much about tuning. :bravo1: :offtopic1: :new1: :spam1:

Hey, I loved my Jr's and also an SG that I had - and you cant get much flimsier than a SG.  That LP was crap.  AND I have heard that complaint from many a LP fan.  Even my cheap copies were nicer.  Heck, just listen to The Song Remains the Same and you can hear Page's LP go slowly flat as the songs progress.

Jimi was ALWAYS in tune.  When the Beatles (mostoverrattedbandinthehistoryofrock) were plinking I wanna hold your hand, Jimi was playing Purple Haze and Foxy Lady.  I think your ears are the problem.

Awwwww, I was just funnin.  No reason to hammer the Beatles.  I have heard the Les Paul problem before, just never had the problem.  Truthfully, music evolved a lot between I wanna hold your hand and Purple Haze.  From 1965 to 1970 Rock changed dramatically.  Not as much as it has currently.  Now Rap is rock and I know you love it.

You are correct tho, there is something wrong with my ears, but not enough to know that no fretted instrument can be in tune.  I had a friend get rid of a GIbson LP and got the Ibanez Gold Top copy back in 77, the lawsuit one with the open book headstock.  That was a sweet guitar I have to admit.

I've had that problem for quite a few years. But now I have a note from the doctor. On my last audiogram the doctor wrote in the comments "...significant loss in both ears for the human speech frequency range." I've pulled that card several times already!   :icon_biggrin:
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

I'll just throw my LP down a flight of stairs and press RECORD

It's about time you gave up on that jazzy crap and played some rock....

Hold up some, you are having too much fun.  If I ever say anything you interpret with that mind of yours that seems as if I am directly poking you, be assured in your mind I am. :l2:
AH HA,,,,so I'm not crazy.................... :think1:

It's about time you gave up on that jazzy crap and played some rock....
I knew it....
That's not jazzy crap.....it's crappy jazz  :icon_biggrin:
BIG DIFFERENCE......actually it's progressive soft soul-funk

I've pulled that card several times already!   :icon_biggrin:
I gotta get me one of those cards  :grin:

Boy I miss a few days around here and I miss a lot of fun! Jim is one stubbornly consistent hombre when it comes to bashing anything other than a Strat!?

Is the tubenit playing your amp SG??? ;)  Overall, it sounds great! Especially your recording gizmo, much better than the 'wreck recording's sound accuracy.

In all seriousness, how loud are you in getting to your sweet (sustaining) part? The only problem is that is was much too short!

Thanks jojo!

Is the tubenit playing your amp SG??? ;) .
Well, the guy's had a pretty big influence on me.....there's no denying that
But, I don't think he's ever had all the volume controls turned up like that  :laugh:
I wanted to play something that he might enjoy listening to.....and the amp plus the backing track brought that out in me..

Overall, it sounds great! Especially your recording gizmo, much better than the 'wreck recording's sound accuracy.
Good...I guess I'm keeping it....it says that the mics are rated to handle 125db
Guess I better put it to the 50 watt test before I commit....... :wink:

In all seriousness, how loud are you in getting to your sweet (sustaining) part? The only problem is that is was much too short!
Well,,,my ears are pretty bad so I don't push them very hard,,,BUT I was able to sit about 6' away from the amp during recording pretty comfortably
There is a very noticeable volume increase when I put the 6V6s back in there.
The combination of 10K in the PI cath. spot and 6K6 output tubes really keeps it at a bearable level.....with the 6V6s in, I wouldn't be able to sit that close
BUT, the 6V6s sound clearer at lower volume settings (2-5).....I don't love the 6K6s until I get them up past 5 and best at 8

Amp volume settings were:
Input volume= 7
OD trim=8
OD volume= 8
Fx level OR Master Vol.= 6

This was the sweetspot where I could back the guitar volume off a tad, but retain that sweet singing sustain,,,and with the Master on 6, the 6K6s were getting hit just hard enough to give up the goods  :icon_biggrin:
To get that harmonic swell I pulled the Volume on the guitar up to 10. (maybe 11   :icon_biggrin:)

Overall, it was nowhere near as loud as my friends Deluxe Reverb RI

I'm gonna do another clip as soon as I iron out some of the things we talked about  :thumbsup:

way into thread, no time to extrapolate,... love tone, ape others requests pickup wise, don"t  like v30s-the 65watt ones anymore than 75s-which i dont care much for either,

 recorder sounds good, just got jam man stereo looper, gunna try n find way to record clips myself-got good camera/vid but sound sucks, battle o band drummer line worthy of spinal tap,

 just turned 53 i think...did some of  those tunes after laying floor 8-10hrs-friends got back from greece to find hvlp leak through house/studio while honeymooning, traded cash n studio time for floorwork.

way into tone-you think w/tube switch, n maybe actual switches amp will be ok for studio/live rig? looking for amp to build for buddy jim to shut him up about damn cornfords. apologize for lack of punctuation, et al, but leaning over bed to type 1 handed.

that is tone i think i want-gotta play it myself, but was thinking about building zendrive or dumble type box-nah...might as well jump in.

1 important thing..does it track fast, or mush if you play fast. bet  it would sound good w/12''x 10'' greenback, n jensen or eminence type in one box-maybe closed open affair.

strat facts; slid a 3bolt down stairs, retrieved it, stretched g string-in tune!
the one i swung on a unruly bar fool fared just a little worse.   

in summation---i want that tone........i think.

and sincerely thanks for all the creative input  lt...snp
keep on with those scales and that fish is gonna die, if it don't bite you first!

never fried a tranny ..till I built a dim bulb tester. UPDATE-haven't fried anything since learning how to properly build & use one...thanks Uncle Doug, & el34 World

1) way into tone-you think w/tube switch, n maybe actual switches amp will be ok for studio/live rig? looking for amp to build for buddy jim to shut him up about damn cornfords. apologize for lack of punctuation, et al, but leaning over bed to type 1 handed.

2) that is tone i think i want-gotta play it myself, but was thinking about building zendrive or dumble type box-nah...might as well jump in.

3) 1 important thing..does it track fast, or mush if you play fast.

4) in summation---i want that tone........i think.
1) I'm gonna try to make it work with switching,,but right now, I liked the 5879 cranked and that definitely creates a volume balancing issue- for me
2) I really like the tone, but, this first clip doesn't do it justice...I've changed a couple things (and then changed them back)and it definitely sounds better the closer you stay to Tubenit's design!
3) Mine doesn't track as fast as it could...I originally set it up to be run with the 6K6 tubes,,,so I used a 4.7K dropping resistor between the plates and the screens (to be gentle on the screens),,,AND to act as a "sag resistor", so I could get a little bit of the sag feel .....
This is more of my "retirement" tone than any speed demon tone....I want to be able to feel the response and let the notes bloom
I've listened to your sound clips, and I'm no where near as fast and clean as you are  :thumbsup:,,,, SO, I would recommend that you would stick with 6V6 or bigger bottles,,,SS rect., with  a lower dropper there,,,, and another benefit would be higher voltages to make it through to your preamp, so you could get a little more headroom .....Tubenit's original design has the lower value dropper
4) It's definitely worth a listen...I've pushed 12AX7s pretty hard trying to get an ultimate OD tone,,,,BUT the 5879 adds a quality that you can't get from a 12AX7.......I'm using it as more of a "late stage boost", by running the "clean" channel pretty dirty, and then adding in the 5879 for the over the top tone....

I've spent a lot of time recently with this circuit on the breadboard,,,and some of the things I thought would work didn't, BUT some of the new things I've tried have just improved slightly on my version of T's very nice design...
Here's a couple notes:
- The 10K shared cathode resistor in the PI (my idea to drop volume) works to reduce the output volume, but takes away from the purity of the tone (no surprise), and contributes to some of the "boxiness" that I described in an earlier post....I've now switched that back to more of a stock value of 820R and the amp sounds much more open and natural than it does in the clip
- The 6K6s sound better as they get cranked (and I really like the OD tone), but I think the 6V6s sound BETTER- (more articulate OD tone) across the board, in all volume settings (I just can't handle the higher volume)

Keep an eye on this thread....I'll continue to update the schematic as I tweak it further :

"Retirement tone"... there's a keeper!    Thanks a lot for all your input, and time.  It seems like the perfect project to start in my old super 60 Chassis. I guess I'll have to move the preamp tubes to the back but no big deal. I earned enough Valentine$ day points to have my Girl  help clean upmy shop.Maybe I can get started today. I've only got 2 pair of 6 v6 left, and one of them is in my 5 E3 but I've been needing a good reason to pull on a couple of those hi output pairs available on site here, Electro Harmonix think. I'm going to download the schematics , I'm pretty sure I have everything except for VVR, but I'll check and cross-reference a bunch of power transistors I saw last night I might even have that, or close. Come to think of it I may have started A TOS board a while back. I might be closer than I thought. I've gotta build something to show up damn buddy jim to quiet him down about those corn Ford amps. Maybe I'll call mine Chevy PEAS.


 Wow just found the double space bar on my phone, I guess I'll apologize in advance for that last politically inKowrecktness

Thanks Plate!
Funny thing is...my playing kinda reminds me of your playing and vice-versa....

Things have been pretty busy here and I haven't gotten back around to recording any more clips.
But I did try recording a different amp (50 watter) with the DR-05 and I wasn't happy with the performance.
I couldn't get the input volume up past 5 (out of a possible 100) without clipping the input....and the recording came out sounding very sterile and muffled,,,,,so this thing might be going back real soon..
If I put it across the room it doesn't clip, but it also doesn't sound great unless the speaker is fairly "close-miked"

wow, tried to respond twice...once, days ago, second time minutes ago, and some glitch erased my response.

going to take the hint, go back to shop, return to build, and try later.
