Posted this in the amp section last week, somebody siad I might have better luck here..... Maybe someone has done this before......I play my 78 SF twin with the master volume all the way up and use only the channel volume to adjust. When running like this, when you pull the master volume knob the boost sound is awesome. Yes it sounds like crap with the channel volume at 10 and gradually raise the master volume, but not the other way around,,,at least not on this Twin, the SFT 78-81 pull boost knobs seem to be very different sounding than the earlier ones. Okay, my question, I would like to mount a 1/4" jack (or equivilant) in the back of the chassis and wire the pull/push switch portion of the master volume to the jack and operate it with a foot switch. Anyone ever done this? or is it possible ?
