I bought the EMG Geezer P/J set to swap into an inexpensive Ibanez that I want to use as a "workhorse" bass. I need to have the versatility to provide the mellow vintage P sound and also the aggressiveness of a J. I've played with a half dozen makes and models of the P/J and generally liked most of them but until I tried the Geezers was never actually excited about them. After just a few minutes of playing I knew these were going to be a permanent part of my tonal apparatus. After 2 weeks (20 hours) of additional playing, I'm more sure than ever. I'm not tech savvy enough about pickups to know what goes into making them sound like they do. I just know these are what I've been imaging as the ideal tone for the live music that I usually play. I'd previously been happiest with the EMG active P/J set and preferred them over any of the various genuine Fender versions or off brand passives and actives. But they had a very slight harshness in the J and I felt the P lacked authenticity and was a bit too clean and modern. The Geezer set is surprisingly quiet. I was worried about that and almost passed on buying them because I've never played a passive J that didn't have an unacceptable level of buzz. I'm glad I gave these a chance.
