I played a Fender P5 that was modded with a Bartolini pickup and two-band preamp. The salesman told that bass was a monster, and he was not blowing smoke! The preamp gave the classic P- bass tone a nice active or modern edge and it really lived up the slap tone while still keeping the Precision identity. This has got me thinking about ordering Carvin PB5 with active electronics and just the split pickup. That said, Carvin prices are so low, it is hard not to throw in the Jazz pickup too.
