Installing a Sadowsky Pre-Amp hidden in a Fender Jazz Bass

Mr. Crumpler is a working bassist with a fondness for the Fender Jazz. This instrument, his most recent acquisition, needed a wider frequency range and higher output to suit his style of playing and match his tone appeal. Trevor removed the stock pickups and preamp, and installed an ivory (color, silly, not illegal endangered species materials!) EMG J Bass pickup set. Under the hood, he wired in a Sadowsky preamplifier and routed the back of the body to accept a battery box.

Mr. Crumpler tells us that the end result has turned the original signal upside down!
