The EVL Honker is this High-Gain pedal in a box you need. It's basically a vintage hot rodded Marshall Guv-Nor. Think about a hot rodded JCM800 in that small enclosure.

The three knobs are classic controls, Level, Dirt and Tone. The toggle switch gives you access to three voicing modes (Normal, Mid boost High Gain and Vintage High Gain).

Power consumption : 11mA

Voltage : 9Vdc center negative.
