Hi there, I've always been interested in the PU configuration of Billi Sheehan's bass, with the P-Style splitcoil in the middle and then a humbucker in the neck position a lot further up than usually done. I've never played that particular bass because I'm more or less exclusively on 5s and 6s. I usually single the neck pickup on my basses - to an extend that you could disconnect the bridge PU and I might not notice for years. So having the choice of a PU in the middle plus one right at the fretboard sounds interesting to me and I'm a bit baffled that no other company builds anything like it. From the looks of it, i'd wager that you have something like the opposite of a PJ config, where you can dial in the other PU to increase what the P bass lacks in lowend instead of getting adding the trebly and clangy sound of the J bridge pickup. Is it too boomy? I guess Mr Sheehan is bi-amping his setup because of the two outputs he uses, but you can also get mono output. . . So why did this concept not catch on ?
