I mean, it's a practical pedal. There's no snake oil or special voodoo going on.
One side is a Green Russian Big Muff with an extra knob, which lets you change what part of the EQ curve the tone knob is affecting. Solves the #1 problem with big muffs, the useless tone control.
The other side is a pretty standard Tone Bender. It cleans up really well, pretty honky and spitty when you push it. It has a lot more bite but is completely lacking in the smoothness of the big muff, so I like to stack them for high gain. Alone, it has a lot going for it for clean sounds that get dirty when you dig in.
The middle button is an analog ring modulator. I don't know why this is on here, its a super niche sound compared to the fairly standard fuzz, but it's fun. Glitchy.
I think the tone bender side makes it worth getting this over the standalone hoof, I use them both a lot.
