Audere JZ3 2 Band Preamp
I bought this here on Talkbass with plans to put it into one of my Jazz basses, but ended up using that bass to fund a Lakland. The knob configuration is Volume / Blend / Bass / Treble. The jack is on the plate, so this should drop into any passive Fender Jazz. All original packaging and documentation is included. I didn't install it and would like to sell it for the same price I purchased it for - $115 shipped to the lower 48.
