The Peppermill is a simple, transparent overdrive pedal designed to create a natural and bluesy sound using minimal components. It can be used as a booster for an already driven amp. The circuit features a MOSFET driving a JFET into overdrive, chosen for their tube-like sounds. The JFET provides a smooth, tube-like quality when overdriven and requires fewer components.

The Peppermill includes a simple R/C filter on the tail of the circuit to tame excess highs and shape the sound into a smoother tone. The resistor and capacitor can be adjusted to alter the response if desired. The end result is a bluesy, “Fender-y” sound with incredible touch sensitivity. Light picking produces clean and round sounds, while harder picking produces a firm bark with lots of pick sound. The circuit responds like another instrument, adding a three-dimensional effect to the sound.

This pedal is suitable for those looking for a stand-alone overdrive to achieve a bluesy sound into a clean amp or to push an already driven amp further into distortion while maintaining clear articulation. It adds spice to your sound without making it unpalatable. It is important to note that different J201 JFETs may produce different results, so auditioning various ones may be necessary for the best sound.
