1988 Boss HM-2 Heavy Metal Pedal Guitar Distortion. Excellent condition and perfect working order.
This pedal produces a distortion that is known from the heavy metal music of the eighties. The "COLOR MIX" tone control is very sensitive and the DIST got a lot of punch. It's a great pedal if you want the 80's Marshall sound without actually using a Marshall amp.
An oddity with the HM-2 is that the Dist knob doesn't actually change the sound betweeen 3 and 8 (assuming 0-10 scale). When you start turning up the dist knob you will hear the amount of distortion increase until the button is around 3. Then the level of distortion remains the same until you get to 8 and then it starts increasing again.
