ok so Im going with warmoth for my next bass and I've decided on a musicman/jazz pickup config. I want an onboard preamp and the u retro deluxe or 5 knob has caught my eye/ear. is it still possible to have control of series/parralel/SC of the music man with the preamp? also could there be a way that I could have the retro, and be able to bypass that and use the stringray preamp? Im just seeing if its possible...thanks!
