As classic as a plate of Nachos,a cerveza and a shot of Tequilla. Three Cascading Gainstages. Three Master Volumes. This one can go from a slight sweet boost, edgy OD, classic 70s rock distortion to classic 70s and early 80s proto-metal crunch. Dime all three masters and get a gnarly oversaturated fuzz. The Diablos respond well to guitar knob input so you can create layered gain working with your guitar and amplifier. Guitar Tres Diablos Ruidosos Amplifier. Keep it simple. Keep it RocknRoll
