| I've actually used a 4-pole jazz pickup in my 1982 Fender Jazz. although, my pole pieces seem huge compared to the ones in the picture. my pickup looks like a single coil version of a music man or stingray. i got mine from Choppersmusic store on eBay. it was meant to be used with active circuitry, but i wanted to try it out and boy did it make a beast of my jazz. it sounds so aggressive i cant use roundwound strings on it because the attack is too harsh. but man, the amount of response coming from these things are amazing. it's like they hit the note before you do. the only thing i would worry about with those pickups are signal loss with string bends and such. the pole pieces might not grab everything. but if they're similar to mine, you'll love 'em. |
