Heavy Pedal is a faithful analog modeled simulation of the *BOSS® HM-2™, the infamous Swedish Chainsaw distortion stompbox introduced in the mid 80s and that sculpted the guitar tone of many metal guitarists.

Current version: v1.1 (November 2019)

This high gain pedal is definitely the dark side in the panorama of distortion pedals. We took our time to find a pristine conditions Japanese version of the pedal (ours is dated 1984) and we modeled it as close as possible.
