I just bought a pair of used Barts from a friend for $20 and help wiring them up. I want to get the maximum potential out of the MM pup, but it looks like the way its wired it cant be split. The J pup looks okay (unless otherwise advised). Theres also the TCT preamp (Treb, Mid, Bass) that Ill try and find schematics for. Any help would be greatly appreciated !!!
