In the words of JAM Pedals:

The RED MUCK mk.2 puts on a few pounds,grows a new set of sharp teeth and is out to seduce even the most demanding Muff connoisseurs!

Inspired from the circuits of the 71 triangle and the later Red Army / Civil War Muff, the RED MUCK mk.2 now comes with a wider gamut of saturation, compression and sustain on tap, accessible by the Boost footswitch and 2-way toggle-switch.
