Hey, I just put a Bartolini 3.3 2band preamp in my Yamaha BB-X. Here are some clips I recorded in the different pickup positions. I appologize that my playing is absolutley terrible, and if I can say so I am normally better. if the links dont work try copying and pasting them into the address. Heres the P pickup only: http://web.ics.purdue.edu/~blavende/PPU.wma Heres the J pickup Only: http://web.ics.purdue.edu/~blavende/JPU.wma heres both pickups: web.ics.purdue.edu/~blavende/bothpu.wma I micd my amp and this is all through my computer, but you can get an idea of the tone.
