You probably recognise the pedal above. That’s because the distinctive black and orange visuals of a Boss compact pedal can mean only one thing: some of the most ferocious high-gain tones available.  

There have been a few iterations of gained-up pedals with this colour scheme over the years, but none more revered than the Boss HM-2 Heavy Metal.
