EX3 - Expand to Peak Tone Control
This is the Artec Expand to Peak Controller Unit. The "EX3" is a scaled-down version of the EXP Unit, and features a Mini 3-Way Toggle instead of a variable control pot. Keeping the switch in the middle provides a clean Flat Boost (no EQ change in your tone, but adds lots of Sustain, and Harmonic Boost). By flipping the switch, you increase the Midrange Peak in your sound. However, if flip the switch to the other direction, you boost the High & Low end of your tone ("Scooping" the Mids). 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 will last more than 4000 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).
