hey all Ive decided im going to upgrade the preamp in my fretless. Thinking about the U retro but would like to know if it will be a simple drop in with my Relfex pickups? Im not sure what model pickups they are, judging by what I found in the search they are Reflex Reds. Anyhow, the preamp that is in it at the moment is a small black box. Im not going to fit it myself i will get my local shop to do it but what do you guys think? have any of you got a U retro with a fretless? or a U retro with Reflex pickups? Cheers Stu BTW, its a PJ pickup configuration. The reason for upgrade is i dont have much top end response or tonal control with the current setup.
