Doppler Stereo combo tube amp

Anybody seen/heard this amp yet?

(I much prefer the tone of the Doppler Vibe mini tube FX pedal they make to this amps tone from their sound clips. Link; http://el34world.com/Forum/index.php?topic=19988.msg209084#msg209084)

Vibrato

 With this asymmetrical frequency vibrato we can hear the full frequency spectrum and original quality of the signal without the phase-canceling signal loss of a typical symmetrical vibrato.
 The Vibrato controls are a Fast and Slow speed switch, pulsing tempo LED, Intensity and Speed controls, creating a variable-speed stereo pitch-shift vibrato from subtle chorus to heavy pulsing vibe.
 A remote Speed footpedal gives variable speed control with a Vibrato On/Off switch.


Power Amp

 The asymmetrical frequency power amp separates the signal into upper and lower frequency ranges and plays them in stereo.
 The KT66 power tube amplifies the lower half of the frequency range through the 15" speaker and the EL34 amplifies the upper half
through the 10" speaker. A stacked Master Volume knob has separate controls for the left and right side.
 The custom output transformer has a special design, perfectly balancing KT66 and EL34 tubes while giving musical even-order harmonic break-up and an enhanced wide frequency range.
 Both tubes have their own external bias adjust.

 Speakers

 The 15" speaker is a Weber 15A200 - a Jensen Alnico P15LL woofer version as used in vintage Leslie rotating speaker cabinets.
 The 10" speaker is the new Tone Tubby Silver Bullet Alnico hempcone.
 An audiophile grade custom-made crossover with air core coils and paper/oil capacitors divides the speakers into their respective frequency ranges.

Sound Experience

 The warm laid-back lower frequencies of the KT66 and slower 15" speaker provide the foundation and background of the soundstage,
 with the brighter and lighter frequencies from the EL34 and faster 10" speaker floating on top into the foreground.

At $4k, I imagine I won't see too many of them floating around.

It's an interesting concept they have, but someone is making a modern Leslie with actual spinning horns (and digital sim of the woofer rotor) for less than 1/3 the price.

I've recently come out from under a rock and discovered Strymon... While still expensive for a pedal, I don't see how the sound & versatility (for capturing different rotary flavors) of the Strymon Lex can be beat.


Someone is selling a Strymon Mobius in my local Craigslist. While the price is good (compared to the new price), and though I want several Strymon pedals which will total to more $$$ together, the flexibility of the Mobius is too much of a good thing to me. Too many sounds available, too many ways to modify it, and suddenly I'd be lost trying to set it up. I think Strymon has something great in their more-limited pedals, with fewer knobs/parameters, but also having hidden functions you can access to really tweak the sound.

Sorry for derailing the discussion...

Not at all, good points/comments, but what about the sound from the amp clips? (When I 1st read about the Strymon in TQR mag. and heard sound clips I wrote Ed C. about it.)

Did you look at/listen to his micro tube pedal?

To me it sounds much better than the amp, well at least from the sound clips.

I hear trem mixed in with the pitch shift.

I'm wondering if it's because he knocked the vibe signal out of wack, asymmetrical?

And the 2 different power tubes in PP, KOC has written about being able to do that with no problems to the OT, if you have individual bias pots.

And the cross over feeding 2 different size/brand speakers.

Had a few more brain cells firing when I wrote about the Sigmund amp in this post.

I didn't before, but did after this post. Agreed that it sounds much better, mainly because the effect is more pronounced.

Overall, all the clips sound like tremolo to me, with some amount of phasing added. I don't hear anything that sounds to me like true pitch-bending. For that matter, Strymon claims the same in their sim of the early Fender harmonic vibrato when they demo it in the Flint. They call it phasing overlaid on the tremolo.

I'm with you, but if there's a common OT there's no way to claim one tube feeds 1 speaker while the other tube feeds a different speaker. So I'm guessing Siegmund went the hard route of 2 independent output stages (or that their claim is inaccurate).

Well what ever it is I like that pedal's sound.

Agreed.  I don't see how, he says; 38w with 1xKT66 and 1xEL34.   

I think he's being liberal/inaccurate with his wording?

Class AB push-pull 38 Watts KT66/EL34
Tube rectifier 5AR4/GZ34
Octal preamp tubes 6SL7 and 6SN7

I don't know.

I'm not inclined to figure it out, since a pedal sounds better than the amp (sound clip, anyway) does. 

I'm also not convinced the Siegmund pedal is "best of breed" for that sound either. But maybe I'm just irritable because my son is driving me bonkers.

I would just like to try and knock the Warblers signal out of symmetrical into asymmetrical.

This must be how reverse-engineering Dumble's gooping must have gone...

See the other thread; I think if you want "asymmetrical" you'd be changing the LFO shape, which has nothing to do with the SR-controlled signal path.

I also think at best Siegmund copied a Fender circuit, not the Hammond circuit you're wanting to tinker (as PRR notes in the other thread). Or maybe he copied some other phase pedal out there, since you like the pedal's sound better anyway.

Yes, I'm sorry, I didn't mean to get these all mixed up.     

I'll answer you in the Warbler thread.
