I just watched your video... you need to be, and can be, more aggressive with your chopstick in specific areas. I beat the shit out of any new build's solder joints to make sure that all connections are secure...poke hard at the pot eyelets , pull on the wires, etc. I've heard this pop dozens of times, and it always comes back to a bad solder connection.
Will try that tomorrow. The point is that I actually do not know when I'm supposed to hear hum when I use the chopstick or not. I mean, there are certain spots that carry high voltage and hence WILL produce noise if I bang them...
Anyway, I'm just back from my three-hour rehearsal. I played the crap out of this amp, with and without pedals. It sounds good. I didn't get any fancy noises. But the pedals do pop. That's a fact.
I noticed one thing at one time though: I had a hum (amp pushed with everything on 9) and then I had the idea to touch my strat pickup and the hum stopped. This happens, right? But then I had the idea to touch the chassis, and bang, the hum stopped too!!! I mean, wherever I touched the chassis with my finger, the amp stopped humming. I tried to reproduce that later on tonight but I couldn't make it happen again. No finger/chassis interaction anymore...
And one last thing: jeez the PT gets hot as hell! I touched it half an hour after having turned the amp off (it had been turned ON and played for two hours and a half) and I couldn't keep my hand on it for more than three seconds (yes, I counted!) Ain't this weird? I mean, the amp has a Heyboer/Mojo export PT that is the same as the one used for tweed Bassmans... And I don't remember a previous Bassman build making the same PT (and hence the chassis!) so hot!!!
Oh well... Please shoot with your ideas!!!
Thanks!
