I just bought a Peavey RSB from Reverb. I got a decent deal on it because it has everything but the guts. It uses two active pickups and three holes for pots. The factory setup for these is Volume Blend Tone, but since I'll have free reign on control options I though it would be fun to crowdsource some ideas and double check what I feel like I've learned so far from my research. First, since the pickups are the only active part of the circuit, am I correct in saying that you can wire it just like a passive bass with the addition of a battery before the jack? Second, the only difference in the choice of pots is the amount of resistance? So, I would use 25k or 50k instead of 250 or 500. Third, I could go V B T like the original setup. I could also very easily go V V T. How difficult would it be to do something like V/T V/T (with a cap or dummy switch over the last hole) or V/B T T so that each pickup has it's own tone knob? Would active pickups have the same issues with signal crossover as passives? If so, would you just add transistors like with the 60's jazz setup, and what values would you use? Would they need to be different like the pots? Fourth, are there any other control layouts that would easily work with 3 holes? I have thought about preamps, but I like the idea of 3 bands. It doesn't seem like there are a lot of options for 3 knob, 3 band preamps for active pickups. I'm also not trying to spend $100+ to put guts back in it right now. It's a strong possibility for later. Thoughts on models that would work?
