The Brontoboost is a two stage booster/fuzz/OD/Dist unit that has a ton of different tones in it, all good! It goes from awesome treble boost like a British top booster, to fullrange boost, to very fat fuzz and everything in between. The fuzz can be set to 'sick', which sounds like an amp on the verge of meltdown! The Brontoboost features tremendous sustain, with a fuzz character that is textured and harmonically rich without sounding like existing fuzzes. Be careful, playing in this compressed , swirly fuzz mode can be addicting, and might bring out a whole new side to your musical expression! "The Bronto is a versatile beast, and has a character unlike any other pedal on the market. Some people simply don't like it, others think it is the most brilliant thing they have ever played! Weird. It does four things, and all of them very well.
