From the vendor

Clone board of the Dinosaural Cogmeister Overdrive. As Dan Coggin's was quoted in a December 2023 Guitar Player interview, "with all due modesty, my gain masterpiece". If you're looking for lots of overdrive options, but are tight on space, this three-in-one unit can cover gobs of territory, with three different gain sections available; - First in the chain, a single transistor boost, - Followed next by tub amp-like drive, which includes a 3 position mids switch, - Finally, a solo boost at the tail end, for when a bit more oomph! is required.

Use one, two, or all three. From light transparent boost, to touch sensitive overdrive, or flat out crunch, it'll knock your tonal tube socks off (along with a few pedals off your pedalboard!).
