My first efx pedal build

That would be a cool project.  That old BC Rich I picked up has a great sounding, simple little 2N5088-based pre and varitone circuit on a board...

That sounds interesting, any wiring diagrams handy?

I was thinking of making a preamp for each pickup, so I'd avoid pickup interaction when I use both pickups on. I'd probably put the preamps after the pickup volume pots so I can use 500k pots for both active and passive mode. I know its (slightly) better to put the potentiometers after the preamp, but then I would be commited on using 50k pots, and those don't work well on passive mode...

All the schematics I've come across depict that pre-amp/varitone combo board as a "black box", without any detail.  There were very few components on the board - mainly caps for the varitone, and I'm pretty sure the pre-amp section resembled something close to the example shown here: http://www.phoenixcomputerlabs.com/All-About-Mixers/Pre-Amps.html

Neal Moser's site has the vintage BCR schems that depict the remainder of the wiring, and also the detail on varitone cap values:

Great info, thank you!
