SuperJ #001 P/J w/ U retro-deluxe preamp, reversed headstock, and RMC piezo bridge-freakin awesome [/quote:2nldsfrc]
The electronics package in your Super J is exactly what I wanted to put in my fretless 73 P Bass. (with a J pickup and eventually a piezo bridge.)
Last summer I installed a U-Retro in it but after a couple of weeks I removed it because I found that I preferred the classic passive P-Bass sound.
I was curious, though, how did you work the piezo bridge into the U-Retro scheme? It's only designed for two pickups, isn't it. (I assume this is why you have a U-Retro instead of a J Retro.)
By the way, if anybody wants to buy a slightly used short-shaft U-Retro (non-deluxe), let me know.
