I'm working on the specifications for a fretless Overwater J-Series bass, and this time I will include V-Bass interfacing. The best bet seems to be RMC's piezo saddles and Poly-Drive preamp. The bass will have a U-Retro preamp which according to RMC doesn't go that well with the piezos (they prefer passive pickups and their own eq unit). My thinking is however to keep the front of the bass as clean as possible, as few controls as possible. If I use the piezos for the V-Bass only (no blending with the magnetic pickups) the minimum integration should be to supply the magnetic signal on the right pin in the 13 pin connector and have a synth volume pot next to the U-Retro controls. Do you think I'm sacrificing anything by not using the piezos for the analog sound? Should I have some more controls on the bass (patch up/down etc)? Is there someone with experience from the RMC/V-Bass combination, does it work at least as well as the GK2B pickup? Any info or comments would be appreciated.
