I didn't want to add this to the "best jazz bass pups" thread because I am no authority on the subject. But I did want to share because I'm really happy with these. Background: I was a die-hard P-bass guy for years. Finally got an American Std Jazz Bass (see avatar) in Feb 2011. I loved it but the hum was really bad at my apartment, and I couldn't shake the feeling that there was a "thin-ness" to the sound as well. I like passive pickups. Shopped around and found great reviews for these, decided to give them a try. Results: Just what I was hoping for! No hum. More bass and low-mids. Using both pickups, it sounds like a really nicely EQ'd Jazz Bass. Using the neck pickup, it can cop P-Bass tones much easier than before. And the bridge pickup solo'd finally gives me something usable - didn't dig it at all before. This baby is truly my #1 from here on out. All the sounds I need in a playable, balanced bass. I'm so psyched. Thx for reading.
