I've been talking with a local luthier/pickup designer about my tone. He's seen my band play several times, and has already designed pu's for my guitarist. I had Seymour Duncan Quarter Pounders in my old bass, and he's convinced me to go with this new design he came up with. So far I'll be the only one to use these, and he's changing the wiring to suit my style. His company is Stonewall Pickups, and he's starting to garner some attention in the 6-string world with his P-90s. I'll be sure to do an in-depth review for you guys, as I have no idea what 5/16" pole pieces will do! What do you guys think?
