I just bought a Fiesta Red Fender Kurt Cobain Mustang. The bridge position Seymour Duncan JB is dark, muddy, undefined and compressed. I cannot currently get a satisfactory bright, cutting, crunchy overrdriven sound. It sounds as if the tone control is rolled back, even though it is dimed! I am considering swapping out the JB for something else, but don't know whether to get a humbucker with standard Gibson spaced pole pieces or a Fender spaced Duncan Trembucker. <br /> <br /> The bridge on the KC Mustang is the Fender Adjust-O-Matic bridge, which is similiar to Gibson's Tune-O-Matic.<br /> <br /> Does anybody know whether the stock KC Mustang is regular spaced or trembucker spaced? The PUP cavity route is very tight, so if the current JB is regular spaced, I fear a Trembucker spaced replacement will not fit.

Think I'd look into the pots & cap and see what's in it.<br /> <br /> I've got SD JB's humbucker (Les Paul) & single (Strat) size and they were far from sounding dark or muddy.

I may be late to the party, but if you get pickups with any tremolo, most of the pickups should be a 'F' spacing. This refers to the Floyd Rose unit and almost every trem unit uses that spacing. This way the pickup poles will align to your strings. <br /> Sorry that no one had jumped in and addressed your question, but I believe that you will find a good amount of support for this comment. <br /> On a lot of my guitars, I use a Floyd spaced bridge pickup and have better alignment there and will use a standard spaced pickup for the neck position with consistent string/pickup alignment. Even on some import tremolos, I will still use this formula as it is the pole pieces that vary slightly and not the pickup dimension. <br /> So, I think you can feel confident with this idea. <br /> Best regards, Woody

Are the F Spaced pups the same size as regular spaced; i.e., is the entire pup wider or is it just that the outside pole pieces are spaced wider. I am worried that if I buy an F spaced pup, it might not fit in my Mustangs pup cavity.

It's strictly polepiece spacing. The overall size of the pickup is identical to a "non-F" unit.<br /> <br /> It will be a direct replacement with no modifications necessary.

Ironically there were some USA made Gibson guitars that needed F-spaced HB'rs. It was the Schaller bridged ones.

I don't hear a difference between regular & f-spaced pickups.
