The preamps in them, I don't find that great, but I do like the pups themselves....(run passive)
If you'd like to try some experimenting first before a pup or preamp purchase, you can try what I did (that I really love)
- I gutted it completely, and wired it using a Jazz Bass wiring diagram Vol/Vol/Tone
- put a fake switch (producer's switch ala Lee Sklar), that can fool even the best producers - hahaha, in the remaining hole
I swear I can flick that non-connected switch, and producer's will say..."I like it better in the down position" - hahahaha!!!!!
Just an idea, I really love my Edge now.
