EDGE Info (Legacy product)

stephen4206

There is a sweet spot on almost every tube amp or overdrive pedal most guitarists know well. A magical zone where the circuit goes non-linear and starts to saturate. Harmonics excited by this process make everything sound alive giving the player a unique interactive experience with great tough-sensitive dynamics. The EDGE is a pedal specially designed to explore the sonic magic that happens when a circuit is pushed to the edge of breakup.


The EDGE is voiced to give a rich blend of saturation, harmonic excitement, light compression and then, at max gain, start to fully breakup.


At lower gains, sweet clean tones are easy to come by, in the spirit of several popular vintage preamps, and could easily be used as a slightly colored clean boost. The EDGE has been designed to give a slight bit of vintage character while offering advantages of modern components and design, such as high headroom dual rail power supply (up to 36v of voltage swing!) and musical, sweepable 18 db/octave filters.


What makes the EDGE's wide sweet spot possible is a set of carefully curated clipping LED’s, specifically chosen for their smooth clipping characteristics and wide saturation curve. The LED’s light up when driven past the edge of breakup and this give us the opportunity to have a real-time visual of how the circuit is overloading. We made this LED visible on top of the pedal, effectively functioning as a visual threshold light for the EDGE of breakup.


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.
