The name says it all. This pedal yields that classic distortion that’s full of girth. Controls include Gain, Volume, Tone, Shape, Bright Switch, Bass Boost, Boost Volume. You can tailor all those classic tones and beyond. The Shape control is a powerful tool that sculpts the midrange frequencies over a wide spectrum of possibilities. Then….add in a clean boost after the distortion circuit that can be used seperately, or as a solo boost! The possibilities are endless. There is no opamp or diode clipping in this circuit.
