Fuck Yeah!!!
Fitting them was a breeze. I was initially skeptical of the solder less design, but they seemed to plug in quite firmly. Time will tell I guess. I ended up only having to solder the jack socket because my bass has one of those barrel sockets. No big deal.
No damas whatsoever fitting the actual pickups in my Squier Jag. No modding at all, everything lined up perfectly. The access hole for the bridge Jazz pickup cavity was big enough for the cable plug to pass through into the control cavity. Neck Precision pickup again fitted perfectly, and everything reassembled without a problem also. I couldn't use my original splined knobs because of the solid shaft pots that came with it, but I knew that they wouldn't before I ordered them. I ended up ordering some genuine Fender Jazz bass knobs with the set screw fasteners. And also ordered a genuine Fender 3 hole control plate because the original one on the bass was a 4 hole plate. Stupid fucking bass boost circuit. Why the fuck did they bother putting that crap in? Useless and it sounded like shit
Now how do they sound? They are Geezer Butler pickups, but I don't have his rig or his fingers so I'm not going to tell you they nail his sound perfectly. They are very quiet, no hum whatsoever. I think they would be great for playing a lot of styles of music, not just the heavy. Very full sounding pickups. They have a nice balance across the sound spectrum though they have a nice lower mid presence. I'm guessing the sound will cut through nicely in a live band mix. I'm not in a band so I can't tell you for sure. The P bass pickup sounds very much like you would expect a vintage P bass pickup to sound. They have a very nice thump. The J bass pickup has that midrange growl that you want from a J pickup. Combined the sound is fantastic all the way up the neck. Great for riffing down on the far end and middle of the neck. Nice growling lead lines up high on the neck. Sound nice through dirt and fuzz pedals. Don't know what else to say but I like them a lot. I would give them a 10 out of 10. The original pickups with the bass boost crap I would of given a 3 out of 10. And that's being generous. But don't take my word for it. Read the reviews. Check the Talk Bass forum. There is a 50+ page thread on them over there. Far more love than hate for them, but you will always get some knockers no matter what.
It is still early days and I'm still setting everything up, but it's close to perfect. I love these pickups. Buy these pickups if you want a vintage bass tone but with a modern punch and noiseless sound quality.
Just so you know I don't work for EMG or Fender.
