The details can be seen here: CLICK HERE FOR SPECS I originally bought this because I thought that I wanted to mod a Squire Affinity V, but I ended up just returning the bass and it was too late to return the pre. It has never been installed and comes with pots, output jack, battery clip and knobs. $70 plus shipping through PAYPAL.
