Pettyjohn Iron Overdrive Pedal

The Pettyjohn Iron is the first offering in their new single pedal format, The Foundry Series.

It draws inspiration from the left channel of the flagship Signature overdrive, The PettyDrive.

The Iron is built with the same audiophile components as its predecessor so it retains the smooth, harmonically rich edge-of-breakup tones found in the original.

The Iron has been voiced to provide a large range of gain and tone shaping.

This compliments any playing style and be at home in any rig as a foundational part of a player’s sound.

The Iron transcends normal shortcomings of many overdrive pedals found on the market today.

Thiis because it features a full, natural tonal range that allows your guitars tone and playing nuances to shine through.

It does this while imparting punch and depth  often associated with cranked American style amps.

Huge internal headroom and carefully selected parts gives an open sound with less compression.

At times, you may even forget you have a pedal on as the sweet harmonics and saturation may just become a part of your base tone that you never want to plug-in without again!

Here is the vid.


  • Wide gain range with 3 wide sweet spot zones:
  • 1: Low Gain Harmonically Rich Preamp/Boost
  • 2: Touch sensitive, Edge of Break Up
  • 3: Fully saturated Lead Channel Overdrive
  • Clean Mix control: Features a warm bypass preamp circuit for adding extra depth and transparency
  • Clipping Selection: Three carefully selected Clipping options for distinctly usable breakup characteristics include MOSFET, LED, and Asymmetrical Silicon
  • Low Cut Selection: Three carefully selected Low Cut frequencies interact with the gain control and clipping section to provide easy recall for different guitars, amps, even bass!
  • High Cut: Musical passive tone circuit with an Orange Drop tone cap for authentic vintage amp style tone shaping


  • High Performance Power: Dual-rail power section with 9V to 18V operation range, providing 18V-36V of voltage swing for huge internal headroom while drawing under 100mA
  • Audiophile, Studio-Grade Performance in a Pedal:
  • Burr Brown OPA series high-performance audiophile Op-Amps
  • Audiophile grade, through-hole 1% Metal Film resistors
