Overdrive
The Supro Drive pedal sports a simple control layout with Volume, Gain and Tone knobs as well as a toggle switch to select between the different windings of our custom, multi-tapped output transformer—either for high-headroom BOLD sounds, or more compressed, high-gain RICH tones. Taking the overdrive pedal platform one step further, the Supro Drive offers a TRS port for expression pedal control of the GAIN knob. With the expression pedal in use, the on-board GAIN knob sets the maximum value, while a user-adjustable, internal trimmer sets the minimum gain setting. All Supro pedals are assembled in Port Jefferson, NY, USA, featuring custom-tooled, anodized, brushed-aluminum enclosures, 9V battery or DC powered operation, rear-mounted metal jacks, easy-access side-mounted battery drawer and studio-friendly, noiseless (click-free) true-bypass switching.
