So I bought a Yamaha BB200 on here last night (don't have it yet) for the purposes of crazy pickup experimentation and I am not sure what I want to do with it yet. The original plan was to remove the existing pickup and use the existing pickup rout to house two 9V batteries. Then put a reverse EMG active P bass pickup directly above and directly below the existing pickup rout. Inspired by Lee Sklar's double reverse P bass. (Lucky for me, the seller upgraded to a DiMarzio DP127 which is a fine pickup on its own. I'll either re-sell or use for something else.) Then I got a wild hair and started thinking... what if I could actually turn this bad boy into a 3-pickup monster? I'd still do a double reverse P above and below the existing rout, ala Sklar. But then use the space in between for some sort of humbucker. Like a DiMarzio DP120 Model One or maybe an old Peavey blade style T-40 pickup, or something else. If I do this, I would have to rig up the Fender Stu Hamm Urge control setup (see page 4 for all possible pickup configurations.) I'd be going passive, so just master volume, blend, master tone, and then a 3-way switch. That way I could still use only the outer two pickups (both reverse P pickups) ala Sklar, but also have a bunch of other combinations using the 3-way switch and blend knob. Crazy, yes. Still with me? My question is, if I do a 3-pickup bass, I probably won't be able to use active EMGs. Because then the middle pickup would have to be active, too, right? Otherwise the pots wouldn't match up. I don't know much about electronics, so keep it simple for me, but I'm under the impression that EMG uses like 25k pots for their active pickups whereas most passive pickups require 250k to 500k. I'm a dummy but those numbers to me look like there'd be a mismatch combining two "outer" active EMG reverse P pickups and a "middle" passive humbucker of some sort. ^Assuming I'm right about that NOT working, I guess I could either 1) Go with three active pickups or 2) Go with three active pickups. Leaning toward option 2) because three actives would require three batteries (right?) The bass IS rear-routed so there is room in the back, but I don't really want three batteries in there. If I go with 3 passives, though, then I could use the original DP127 that comes with the bass for one of the "outer" pickups. Order a second DP127 for the other "outer" pickup. Then order a humbucker for the middle. Insane right?
