I dare ask this question after recommending against it to many others. I was wondering, because I am well settled with the feel and look of the bass (it's a keeper), whether I would greatly benefit by gutting it and replacing pickups and preamp with Bartolinis. I would also like on-off and passive-active switches, if that is possible. For the most part, I am aiming for a little more oomph and range of expression, if possible. I'd also like to solve the problem of having the guitar go silent (without apparent warning) every one to two months with a case of dead batteries. I have the luthier to do this for me, and I have already upgraded my tuners and nut. This will also solve my problem of ultimately wanting a bass with Barts in it.
