i have an old yamaha bb605 lying around at home, nice playing bass but I don't like the single coils or cheap active electronics, I was going to replace the pups with Dimarzio ultrajazz 5's and the preamp with an audere 4 band eq and passive roll off when it occured to me... why not add a 3rd pup, I've been gassing for a 5 string musicman and after a little photo shop fiddling i think it may be possible to squeeze a 5 string MM pup between the 2 jazz pups. hopefully it'd look something like this although mine is black Thoughts? I'd have to wire the MM and bridge J up to a 3 way mini switch so I can get J-Both-MM option then into the blend to mix with the neck J pup, I'd also love a series/parallel or coil tap option on the MM but since audere comes prewired with mini pots adding a push/pull probably won't be possible. controls would be volume, blend, bass/low mid, high mid/treble, passive tone roll off, z mode switch, J/MM pup selector switch... a lot of wiring and drilling involved! Thoughts? wiring suggestions? am i crazy?
