it doesn't have 6 knobs, it may be a meme pedal, and many have probably skipped past it for obvious reasons, but out of all the "amp-in-a-box" / distortion pedals ive tried so far (REVV G3, Soldano, PG-14, Figment (MIG-50), Tight Metal, Rat, Klon), the 4 knob Face Melter is the most versatile and natural sounding distortion I have tried yet.
Compare to Steel Panther Pussy Melter

it has x2 modes (or channels), low gain and high gain, both are just as useable as each other.
plugged in front of a clean amp channel, the treble and bass controls work well to offer just about any kind of distortion tone you want (except fuzz).
and yep, on the low gain channel setting it will gladly take an overdrive in front and reward you for it \m/ (tight and thick sustain, no bullshit)
evidence:
yes it doesn't have 6 knobs. but this is better than any 6 knobber i've tried.
