Ok, I don't know a great deal about pickups. But, I'm looking at single coil p-bass pickups and I keep seeing these Quarter Pounders that have flat tops and I'm wondering how this is going to sound on a 9.5" radius neck? It seems to me like it won't be balanced. But, this seems like such an obvious thing that I'm imagining that there must be some simple answer that I'm just not aware of. The guys at Seymour Duncan obviously aren't idiots. So, what's the deal? BTW, I'm researching because I'm very strongly considering getting a Bronco and modding it. So, if you have other recommendations for pickups for a Bronco let me know.
I want to put one of these in a Bronco.( already have 2 )Narrow spacing. Perfect. Adjustable poles to balance radius.Waaay more range than most mudbuckers. They're around. Guild humbucker. Re your original concern, flat pole single coil pickups ala S.C. precision and jazz have been going in radiused basses forever.
Are you talking about two section P bass type pickups? Each section only handles two strings. And each end of a section is height adjustable. The inner ends of the pickups can be raised to follow the radius, and often are.
Like such. You're going to find pole spacing an issue on a bronco (narrow). Some have used Rail type Strat pickups w. good. results. The super distortion models have a bass pickup tone profile. Don't let the name throw you a curve, they don't have to be distorted, the big fat bottom just makes it easier to do in a guitar.
I notice a disparity if the flat pickups are close to the strings. Crank them down away from the strings helps. I've also tried "shims" that sit on the tops of the middle poles to effectively raise the pole pieces closer to the strings. That works well if you want to be close to the strings.
flat pickups under radiused bass strings bug me, too; you get hot outer strings and weak inner strings. the only setup fix is to drop the pickup away to where the relative differences in string distance get reduced. (haven't tried the shim thing yet, not sure how well they'd stand up to getting hit with fingers or pick over and over.)
The old Hagstrom single coils (not Bi-Sonics) use the shim (more like an extension) approach. The coils are wound around bar magnets, and the "poles" are just little metal pieces that fit in the top of the pickup cover. A lot of people use the SD QP with the vintage Fender radius and seem pleased.
A piece of steel rod the same diameter as the pole pieces cut to a mm or 2 that is attached to the top of the pole pieces with a little super glue as well as the magnetic force. I tend not to play over the top of pickups so durability is not an issue for me. I did this on a Jazz and it worked well. With my MM SR5 I just keep the pickups very low and that works as well.
