QTB - 5-Stage Clean Boost
This is the Artec Quadra Clean Boost Unit. The "QTB" is a built-in 4 step clean boost for Electric Guitar or Bass. It features "quiet switch" operation with a true bypass when not in use, and offers settings for 0dB, 6dB, 14dB, & 20dB of added gain. Easy installation with any Passive or Active pickups in your Guitar or Bass (no modification needed, as it just replaces one of your tone pots). Powered by a 9v battery (1 battery can last more than 3000 hours!!!). You will receive the Unit itself, as it is pictured, with a Battery Clip, & Stereo Input Jack (incase the one you have on your guitar is Mono), as well as a wiring installation wiring diagram (very easy to follow).
