Gorilla Warfare MKII is a beast of a distortion/fuzz pedal by Greer Amps — it’s essentially their version of a RAT, complete with an LM308 chip.
It has three simple controls: Volume, Gain, and Tone. In a previous version, Tone was called Filter but now it has more treble.
I’m a big fan of this pedal, even at lower gain settings, but the money is with the gain, volume, and tone cranked. Yeah, that’s sure to be an unpopular opinion, eh? 😉
