This is based on the blues driver but very heavily modified. DOA stands for Discrete Op Amp (Not Dead On Arrival). The circuit uses JFETs for the input of each of the two DOA’s inside. Gain controls the amount of dirt from clean to nasty crunch, TREBLE, MID and BASS are a classic amp tone stack to perfectly dial in your sound, and VOL adjusts the overall volume out of the pedal. This is great for a clean boost with an edge or crunchy dirty rhythm.
