This Audere JZ3 Pro 4-Band Drop in preamp is brand new. It was installed in my 78 Jazz bass for maybe 24 hours. I loved what is was doing but decided to send off my body for a refinish and when it returned I took the bass back to stock with all original parts and harness. These are $159 new. This is as good as new. I have a bunch of items going up here for sale to help fund an incoming bass. Unfortunately something has to go so here goes some parts that are sitting idle at the moment. $115 Shipped Lower 48 USA Only Will combine shipping for multiple items. See my other listings.
