I'm doing a focus program at my school next year where I get to make my own bass. They supply the wood, shop, and know-how, you supply everything else. I'm looking at various pickup configurations right now, and Gerald Veasley's double inversed p-pickup bass with piezos has me very interested. The entails several questions: 1. Who makes six-string piezo bridges? 2. How different is the reaction to tapping from regular magnetic pickups? 3. How much might a piezo bridge cost? 4. How does inverting the p-pickup change the sound? 5. What companies make five and six string p-pups? Now, about different configs: 6. Who makes MM-style sixer humbuckers? 7. How much might they cost? 8. How do they sound with a p-pup? 9. How might a humbucker sound with a piezo? 10. Finally, what pickup config would you reccomend for me? I do a lot of chordal, lead-type bass stuff, as well as tapping. However, I also do funk and Primus, I'll be doing classic rock covers starting next September, and I'm going to be in the school's jazz band starting around that time too. I would PREFER to run this passive, but I won't object to active pickups or a preamp. EDIT: At the moment, I have a Samick P/J with Basslines SPB-2, SJB-2, and an Aguilar OBP-3. I really love the tone from the SPB-2 but the SJB-2 is just NOT my thing. I may be splitting with the folks on a Yamaha BB404 fretless depending on how well my exams go, and when I get a job later this semester I'll be buying a G&L Tribute L2500 (fretted, most likely, but if I really dig the fretless I'll get it like that instead).
