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.
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

- Treble: +/-16db @ 10 KHz
Bartolini: Preamp: 4.6 Review
By Ryan Sparkman from on 12/27/2013
I had the BART 4.6 and BART pickups installed into a Brubaker Brute (5-String). The BART's (PREAMP and Pickups_ brought the bass to life. Nice sonic control to the bass--added more growl and focused mids. The bass already has a strong Mid-tone.
The only downside I have is the treble. It''s a little hot going through my GK RB700. Maybe it's the shielding. I'm not sure, but if anyone knows please feel free to comment on the post/review.
