Oh, I know you're not picking on me. I believe they collide when you put the neck Jazz pickup where Fender traditionally puts it, but that's not what I meant or want. I mean to put a J pickup where Music Man puts their single coil. Like in this picture of a Stingray HS. The bridge pickup is the same place it always is, the so called sweet spot. You can tell because the pickguard is not any different that one on a normal MM bass, except for the fact that there is a single coil in the neck position. I do believe that that route is significantly further from the bridge than the neck pickup is on a Fender Jazz. So yeah, you couldn't do the standard J neck route, but a totally different one that is closer to the neck. The basses share the same 34 inch scale, but the pickup positions are completely different.
But I get your drift on doing all those pickups in the so called sweet spot. You're right, they are not MM pickups so who knows if they would even work there.
But to further show you what I meant on my original suggestion, here is a Sterling bass whose pickups have been replaced. You can see the bridge pickup is where it always is and that the neck pickup is a J style rather than the original Music Man single coil which doesn't have the same mounting tangs a J pickup does, but is pretty close to it in dimensions.
Heck, while I'm at it, Warmoth doing a MM style pickguard would be cool too, and yes I realize that the control route is completely different from a Precision, but since this is all pie in sky stuff anyway, why not? As has been mentioned before in this forum, there has been 3 maybe 4 suggestions from members/customers that actually ever got implemented. So yeah, but I guy can dream, right?
