Here’s my question: first of all, I hope this is in the right forum. If not, please feel free to move it. I’ve been consumed with the idea of a Fender P/Musicman Stingray mash-up bass for a while now. I’ve read the forums here (http://www.talkbass.com/threads/musicman-pickups-in-a-jazz-bass.594934/) and on other threads about the do’s and don’ts of mixing the two different pickups. I also do know that Sandberg (http://www.chicagomusicexchange.com/collections/sandberg/products/sandberg-vm4-bass-cocobolo-top) and a few others out there make something similar that can be bought off the rack, but I like the idea of “building” one myself. Most of the threads on the subject start with a P-body and either add the musicman PU close to the bridge which apparently doesn’t do well for sound. Or, they’ll reverse the P pickups and try moving the MM pickup closer to the middle which seems like a routing nightmare. What I haven’t seen (and feel free to correct me if I’m wrong) is taking a Mark Hoppus signature P/J bass with the reverse P pickups that are already close to the neck and then routing in a MM pickup in it’s more natural location. Has anyone done this? Is it possible? I mean, obviously it’s “possible”, but is it a crazy idea? My concerns are multi-faceted: first, there are very few Hoppus basses out there for a cheap enough price to hack away at. Ideally I'd like to find a relatively clean body for $250-$300 but that's proving to be rather difficult. I wrote Warmoth if they could cut and route a Jazz body with P pickups in the same location as the Hoppus bass and they said no. So, it’s either find a good used body or find someone who will custom make one (willing to accept bids from experienced luthiers ;-)). Second, working out the electronics. I wrote Aguilar about their pickups and preamps and they said the OBP-3TK/PP preamp with their pickups and toggle switch would work. The idea is to have a volume, treble, mid, and bass knobs with a toggle switch to go between P, MM, and then P/MM blend on the pickups. This would require custom cutting on the stock Hoppus pick guard or possibly using a jazz deluxe chrome plate and cutting in for the toggle switch. What says the crowd? Is this a crazy idea? What are your thoughts?
