GUITAR FUEL is proud to offer the SBK Series of active preamp/equalizer (EQ) harnesses for guitar, bass or any piezo equipped instrument. Manufactured in Korea using top quality components including JS and ALPHA potentiometers, Teflon coated wire and SMT (Surface Mount Technology) they come in both 2 and 3 band models. They are a complete easy to install solution which provides +/- 12dB control for each frequency range.

Unleash the power and tone of your pickups!

Both the SB-2 and SB-3 include a version with a reduced number of potentiometers by combining functions with the use of a concentric potentiometer ("A" designation). The SBK-3A is a full blown parametric equalizer with the addition of a Frequency Range Shift control. The top dawg SBK-3AD reduces the number of controls to just four (4) with the use of two (2) concentric potentiometers. All of our pre-wired EQ harnesses can be upgraded to 18V for additional headroom and/or a passive/active toggle switch so you have options available to create your own TONE MONSTER!

Whether you need a 2 band or a full function 3 band parametric equalizer for your latest
build or instrument upgrade GUITAR FUEL SBK Series equalizers are a superior
"tone to $dollar$" value!
