Well right now I'm saving up for a new Warmoth Explorer bass, but my income is limited, and it could be a while till I can actually make it, so I decided to make my current guitar really nice while I wait for my Warmoth bass money to come together. I have a 94 Epiphpone Accu Bass (shut up, it's all I could afford at the time! :icon_biggrin, which is Epiphones P bass if you didn't know. Either way I'm replacing the tuners, the bridge, and all the electronics, then painting it. I'm going to have it routed for a J bass bridge pickup, and put the jack on the side leaving the third control hole open. I'm putting Seymour Duncan Quarter Pounder pickups on it, and I wanted to put that "black ice" passive overdrive on it, and here is were the problem comes in. It replaces the tone knob with a distortion control. It's really cool, I've heard it in person, and I like it, but it's not right for everything. Once it's installed, you have no tone control. Thats not gonna work. Can anybody help me wire this, I basically would like, volume, distortion, tone, blend, and I guess some sort of switch, or push pot to switch off the distortion and onto the normal control with a normal cap and everything. Is this plausible? I know I would have to use concentric pots but my main question is, can I wire it with two different controls, and switch between those two with a switch like an amp with a dirty channel and clean channel, but on a passive bass guitar. I've got a feeling that this is insane and isn't gonna happen, but if it's at all possible I'd like to make it happen.
