Whether you have played the original pedal or not, you will experience instant sonic nostalgia when you plug in to the ODI, recognizing the tone heard on countless records over the last four decades.

 

The inspiration to make this pedal is a personal one to circuit designer Stephen Pettyjohn. Stephen’s first overdrive pedal back in high school was a 1978 Boss OD-1 and it served as his main overdrive for more than 10 years. He sold it when the prices for an original went sky high a few years ago but missing “that” sound he set out to recreate a pedal that captured the tonal characteristics that he loved about the original while adding the features he always wished he has on the original. 

 

CORE Series Simplicity

The CORE Series features a streamlined control set for quickly dialing in killer tones with four knobs to adjust Level, Gain, Lows and Highs.

 

CORE Series Dual Rail Power

We designed the CORE Series with a dual rail doubling power supply. This design can scale from +/-7v to +/-18v, effecting the headroom, tone and feel of the pedal, achieving up to four times the headroom over standard 9v pedals. The internal supply achieves this by mirroring whatever input voltage you apply via the external power supply and we always encourage people to experiment.

 

CORE Series Quiet Bypass

Our entire CORE Series features our quiet bypass switching system. It is a true bypass, relay based system for minimum pop when engaging the effect.

CORE vs FOUNDRY

CORE Series was announced in 2020 as an approachable pedal line that dives deep into the realm of studio-grade analog boutique guitar pedals while leaving pretension at the door.

FOUNDRY Series is our original 'hold-nothing-back' lineup of studio-grade analog guitar pedals which we fully retooled in 2019 with all-new MKII versions of the entire line. With the introduction of MKIIs we unveiled our industry leading high-voltage power system, a new relay based quiet bypass circuit, custom enclosure enhancements and more.

BOUTIQUE PEDALS

Pettyjohn Electronics is a studio grade boutique guitar pedal company founded in 2014 by mastering and electrical engineer Stephen Pettyjohn.

 

Our engineering focuses on analog signal processing with discrete op-amps, high-voltage power pumps, and custom mods, with all stages using top-shelf audiophile componentry.

 

All Pettyjohn pedals are designed, forged and wired in the USA by our small team of three partners.
