Howdy all, I'm thinking about modding my yamaha 765 with some EMG pickups. i really like the sound of the stock pickups, but i've been getting addicted to that crunch that les claypool and other bassists get from there emgs. anyways, i know les claypool uses EMG dc45s, but i havnt found any of these for sale on the net... i did find some EMG 85s used for a good deal...but are pickups worth buying used? and another question: can i use my existing yamaha preamp? or would i need to gut evreything in order to house the EMGs. thanks for all input on this matter!
