Probably just replaced the knob, though.

Hopefully it's just the extra tubes and new transformer for the added power. The new knob on the vibrato channel makes me wonder if they modded that also. Suppose I wouldn't mind, I read somewhere that it's just a square tremolo and not actually vibrato at all.

Thanks, that helps pinpoint it a bit better. The tube layout in my amp goes: 12AX7WC (x5) 12AT7 6L6GC (x2) 12AT7 12AX7WC The first three preamps are front left right next to the input and the second three are back right which makes me wonder a little. I read somewhere the V2 is actually the preamp f...

I've also found out since posting this that some of the early bandmasters came with 4 spots for 6L6s with two of them capped, and that there evidently was a popular mod to up it to 4 of 'em.

Hmmm.

Oh, here are some pics: http://i267.photobucket.com/albums/ii317/RabitesAngelatin/band31.jpg http://i267.photobucket.com/albums/ii317/RabitesAngelatin/band30.jpg http://i267.photobucket.com/albums/ii317/RabitesAngelatin/band6.jpg http://i267.photobucket.com/albums/ii317/RabitesAngelatin/band1.jpg

Just bought this off e-bay, hasn't come yet. Normally they've got 2 power tubes, this one seems to have 4 of 'em. Didn't worry me at first, these old amps can vary a bit depending on when it was made, but I keep reading about this amp and and keep not finding any reference to a model with 4 6L6s. No...

Hm, is there anyway I can troubleshoot it? Like remove a tube and see which channels do/don't work? Can that damage my amp? Or like...something? ??? Plus I wanna over time here get to know these things about my amp so after the warranty runs out (or, say, emergency on road) I can fix the real basic ...

Maybe easier in most amps, but I've got a Fender Super-Sonic which has two circuits, one based on the Vibrolux, the other on the Bassman. I've been driving the tubes real hard (in the Vibrolux channel) for my overdrive for the last 6 months using a power attenuator. I don't use it anymore and I've g...

Man, I'm in the middle of starting a band where I play a setup like this. Guitar-->a/b splitter SIGNAL 1-->MXR Blue Box w/ blend knob at 9:00 or something, i find a point where it's all gated and gets the notes wrong--> bass head, or whatever's around I guess SIGNAL 2-->Tube Driver 911-->clone of ol...

I really have no formal training. A friend showed me a few open chords in the beginning. When I started playing bar chords I thought I'd invented some new primitive approach to riffage.

I just make shit up.
