Is Duncan JB on a Fender Kurt Cobain Mustang regular orTrembucker spaced?

I just bought a used Fiesta Red KC Mustang. The bridge position Seymour Duncan JB humbucker is very dark, muddy, undefined and compressed. It sounds as if the tone control is rolled back, even though it is dimed! I am thinking of changing it out, but am not sure whether to get a PUP with regular pole piece spacing or a wider Fender spaced trembucker PUP.

The bridge is Fender's version of a Gibson Tune-O-matic and I am not sure if it is Fender or Gibson spaced? The PUP cavity route is very tight, so I assume that, if the current PUP is regular spaced, then a Trembucker will not fit?

Have you tried adjusting the pickup height? Maybe someone unwound the screws too much. Could also be very dead strings.

Check the pots man! Maybe it was setup with 250k pots. Get a 500k or a 1meg pot in there! It should clear up things!

I would think it is normal spaced too, but you can measure it. From our FAQs:
Trembuckers are designed for wider string most commonly associated with Floyd Rose or vintage vibrato bridges (often called Tremolos) with a string spacing of 2.070″ or 52.6mm, measured center of high string to center of low string over the bridge pickup. Humbuckers are designed for bridges with traditional Gibson humbucker string spacing of 1.930″ or 49mm, measured center of high string to center of low string over the bridge pickup.

But the issue is that JB- in no way should it sound the way it does. If anything, it should be barky and bright. Check the wiring first, I think something might be wrong there.

PUP is currently very low. It looks like it is backed up almost all the way.
