Retro-Sonic Distortion.  The Distortion pedal is based on a LM308 op-amp design, features true bypass with Distortion, Tone and level controls providing many tonal possibilities from subtly distorted blues tones through classic rock and metal.

As added flexibility, two internal thumbwheels allow adjustment to the frequency response of the gain structure. When the back cover is removed two thumbwheels are visible: The left thumbwheel adjusts the higher frequency gain, the right lower frequencies. This gives the Distortion user the option to tailor the overall response of the pedal to taste, by reducing or increasing the mix of high or low end content. More tonal flexibility can be explored through multiple clipping options via a 3 position mini toggle switch that selects symmetrical-diode, asymmetrical-diode, or LED clipping. 

The Distortion is built using metal film resistors, film capacitors, and a double-sided circuit board for noise free operation.
