The Best Overdrive Pedals

Boutique audiophile overdrive pedals designed to stack.

Prologue

FOUNDRY Series is our signature studio-grade, hold-nothing-back, boutique guitar pedal line. Unlike CORE pedals which are designed to be played in isolation, FOUNDRY is a synergistic tonal system designed for more subtle and refined chain stacking.

While all Pettyjohn pedals feature audiophile componentry, only FOUNDRY offers our top shelf Dual Discrete 990 op amp mods, our proprietary Pettyjohn 36v dual rail charge pump, and extended tonal controls (including secret internal switches).

In true boutique pedal form, FOUNDRY also offers a wider array of tonal, clipping and op amp mods all packaged in our nearly indestructible, custom built mild-steel enclosures.
