The Cmat Mods Butah is an analog overdrive pedal with a low-gain character designed for pushing a tube amp into breakup. RockBoard's PedalPedia describes it as "a low-gain character tailor-made for pressing a tube amp into breakup nirvana," and calls it "a staple effect for any board"1. It sits in the same family as other overdrive pedals, but leans toward the gentle end of the range rather than high-gain distortion.
What it does
The Butah is built around the territory between boost and drive. according to RockBoard's PedalPedia, "the Butah sidles between clean boost and overdrive with ease for giving a bluesy boost or aggressive bump with the flick of a knob"1. In practice, that means a player can use it as a nearly transparent level lift into an already-working amp, or turn it up for a touch of grit, without switching to a different pedal. Players looking for more saturation would move toward distortion pedals or fuzz pedals, while those wanting even less coloration might consider a boost pedal.
Build and power
The pedal is analog throughout and comes in a powder-coated enclosure, which RockBoard's PedalPedia describes as "ready for the road or local gig"1. It runs on 9V DC with a center-negative plug and draws 8mA, a light load that fits easily on a shared power supply1.
Cmat Mods is a small builder; the maker's Facebook page identifies it as based in Peru1.
Origins
The Butah's origins are modest: the maker's own Facebook page carries the name Cmatmods Pedals Effects Perú, indicating the pedals are made in Peru1. CmatMods describes the Butah as a staple effect for any board, and its character sits between a clean boost and an overdrive, which is where it fits on a player's pedalboard.
