New Mojotone tmb build
Just got finished with the mojotone tmb build. My question is when I am in one channel the volume of the other channel affects the tone of the channel im using. It makes the tone of the used channel sound horrible. When the other volume is turned down it sounds great. Anyone know whats going on

That should not be happening of course. So I suggest that you print a copy of your schematic and of your layout then take a marker and trace the actual build against the schematic first then the layout marking as you go to look for a build error.
It sounds like there is crossover of the signal somewhere. So I think you should start at the phase inverter valve and work back to the preamp stages as methodically as you can. If you do not find a mistake, a short between two points or a bad connection then come back for more advice.
Good luck.
