Using this on and off for like... 15 years? I have always had one of these in one guitar or another.. lol. I like this pickup overall. It is pretty balanced.. pretty hot.... but backs off nicely. Not scorching like a Gibson 500T for example, but still has enough gas in the tank to rock.. without the spikey trebles. Things I like least about it..hmmm. Well, it could have a bit more character.. I would not call it a bland pickup per se, nor would I call it a blank canvas. The overall characteristic would be the fact that it is balanced.. probably a good choice for a studio guitarist.. an inoffensive tone that can do heavy or clean. Ultimately, the benefit of this is versatility.
I've had this in basswood, alder, mahogany, alder with maple tops, mahogany with maple tops, etc, etc. guitars. It has a different character with all of them, but you always know it is a JB. There is always speculation, and reference that this is a "Jeff Beck" signature pickup... it has never been. Not sure, but there was some controversy regarding this as to Seymour trying to pass it off as a a signature model.. not sure how the legend goes. LOL! It actually stands for "Jazz Bridge". Hence, the fact that it is very balanced... good for fusion.

As I mentioned.. I have always had this in one or more of my guitars for over a decade. I would say I am fairly sold on this pickup. I think this is a good value given the prices for Gibson pickups for example... which are no better than this. I would make the same choice.... owning this pickup does not stop me from owning other pickups... if I could only own ONE pickup, I might reconsider .. then again.. I might not! It covers a lot of bases.. it could be considered an all-in-one solution.
