I've just picked up a nice piece of black walnut which would make an excellent pair of body wings for a through-neck bass, so I have a potential project in mind. I like narrow-spaced five strings (like MM spacing), and my idea would be to build a five string with similar pickup positions to a Rickenbacker 4001/4003 with the aim of getting the sound into that ballpark, though it wouldn't be a straight copy in other respects. I'm not looking to precisely recreate any particular model or era of Rick sound, just to get some of that character out of it. I've been looking around at what my options are for single coil pickups with a bit of brightness to them which would work for a narrow-spaced fiver. Classic Amplification have some, but I'd need to check string spacing. Hanson Chi-Sonics could work and would look great. Carvin do their J99 pickup in a soapbar version, and while those are less pretty they might be an option. Is there anything else out there I should be looking at? The other option is to wind something myself - I've done this a couple of times in the past but I find it a bit of a PITA, to be honest!
