This thing is not subtle. The Meatbox is a sub-octave synthesizer that generates frequencies so low it can rattle windows and blow speakers if you're not careful — and that's kind of the point. Originally released in the 90s and nearly impossible to find for years, DOD brought it back and the reissue delivers the same ridiculous low-end chaos as the original.

Great for bass players who want to shake the room, or guitarists running it into a full-range system. Not a one-size-fits-all pedal, but if you know what it does and you want it, you already know there's nothing else quite like it.
