## Overview

The John East Retro Jazz Bass 3-Band Preamp (Chrome) is designed for musicians seeking to enhance their jazz bass experience. This preamp features a seamless fit into standard jazz-style basses, offering a powerful 3-band equalizer, an active blend circuit, and user-friendly stacked knobs for ultimate sound customization.

## Description

The J-Retro 01 is designed to fit directly into standard "Jazz" style basses without modification. Its high quality circuit uses three stacked knobs and includes an active blend circuit plus a 3 band equalizer with bass, variable frequency mid, treble and bright function. A very gentle built-in contour gives immediate color without detracting from the basic sound of any bass. The active blend circuit prevents the loss associated with many passive basses where, when both pickups are up full, the signal from one pickup feeds into the other and vice versa. However, a switch is included to allow a passive equal mix of both pickups. A second switch - basic "get-you-out-of-trouble" passive mode is included in case the battery dies in crucial circumstances, and this mode allows some useful settings too. Easy to fit, no routing or modes to most J Style Basses. A standard 9-volt battery fits under the plate in the standard cavity in most cases.
