Wow !
The bass has Synth driver again !
I am very interested how difference of the sounds RMC PUs and Graphtech PUs. (Metal vs Plastics)
RMC PU size is slightly over size for my narrow 5 strings, that I think.
I can't decided major modify, so my piezo project is minimal modify.
But I believe Rob's bass is one of best way !
