Demon with Octave Jawn Mod.
The Octave Jawn is a polyphonic, digital, fast-tracking octaver. This means that it will track those arpeggios, complex chords, and noodles well. Yes, octavers are widely available, but where we turn left instead of right is that ours will be a drop-in mod.
The right footswitch activated the Octave Jawn. The white knobs set the volume for upper and lower octave.
The Demon is a low to medium-high gain dude with some nice tweaks here and there. This pedal just makes your instrument sound "right."
