Hey, I'm hoping that some of you guys who are experienced with modifying the electronics in your basses will know the answer to this. I have a Pedulla ET-6 that I've had for almost 10 years, recently the tone knob has started acting up. Checking the wiring inside shows that everything is fine. I've contacted Pedulla and It's going to cost me roughly $120+ to have them repair it. They have a $50 minimum for repairs, plus shipping and insurance costs for both ways. Yikes! So anyway, instead of having it repaired, I'm considering having a brand new pre-amp installed. Specifically the Bartolini HR-5.4 which is actually a complete pre-amp and wired harness. My question is this: Will this harness work with my existing pickups? They are Bartolini, so I assume it will. Nowhere on the Bartolini site can I find where it says that you have to match up pickups with any specific pre-amp or harness or anything like that. It's almost like you can pick your pickups, pick your harness, and it will all work together no matter what. Knowing nothing about electronics or pickups or compatibilities I put this questiuon out there hoping that you guys will know. Thanks a lot!!!
