So I'm putting together a multi amp rig. If I can get it working it will be pretty cool: Traynor YBA1A and AC30cc for dirt BF Bandmaster and Bassman 100 in stereo for clean BF Bassman driving a Leslie 16 I have to build a new pedalboard too, my old one is over the hill. For the Traynor and the Vox, I either will build an A/B box or run them in stereo, not sure yet. So I was fooling with it last night, hooking up a Boss stereo chorus, and found out that the Vox and Traynor are apparently out of phase. I thought the pedal was screwy because the led wouldn't light up and the signal to the Vox was very faint. Something is getting grounded out. Experimentation proved the pedal was fine. So I'm guessing I need to build a phase inverter of some kind, assuming that it will fix the problem. I found this schematic online and will give it a try. Any comments or suggestions would be appreciated.
