A Pre-Wired harness saves the time and aggravation of wiring your pre-amp and pots into your instrument. They feature our industry leading pre-amps and premium audio-quality potentiometers with smooth control and ready for years of rugged use.

Bartolini preamps offer many popular configurations available for many control layouts. Tonally the Bartolini preamps are comparitively punchy in the low, low midrange, and midrange. The top end is 'note' bright. These units contain gain control which allows the user to set the signal to output level via a small trimpot on the module.

These preamps are not recommended for fitment in top routed Fender style instruments with the control cavity on the top. Intended to be used with an instrument with a rear control cavity.

*Modification Needed:

Bartolini preamps are built compatible for use with passive pickups such as Bartolini, Aguilar, Nordstrand, Delano, and other passive pickup manufacturers. If using active pickups preamp passive stage of Volume and Blend will need to use 25k pots. A single 9v battery is sufficient to power both active pickups and a Bartolini preamp simultaneously, but we recommend 2 9v wired for 18v if there is enough room inside the bass
