The LIFT MKII an always-on studio grade preamp pedal, being either in Buffer mode or Boost mode, switchable via the new soft touch foot switch.


The LIFT MKII draws inspiration from our previous PreDrive pedal and brings the most loved features to the Foundry Series. It is packed with versatility and can be used with any instrument, not just electric guitar. Give your sound a lift with the LIFT MKII and re-discover your clean tone.


The Buffer You Have Always Wanted

The buffer mode is a truly state-of-the-art circuit, featuring a single discrete opamp powered by our new proprietary dual-rail power supply providing huge headroom and tuned for absolute transparency with frequency range from 20Hz to 25kHz.


The discrete opamp gently ‘lifts’ the tonal quality without unwanted color, unlocking every nuance of your guitars tone with a musical, 3D depth.


An Exceptional Boost

Activate Boost mode with the foot switch and use the Boost gain knob to unleash loads of clean gain. The LIFT MKII Boost mode provides up to a whopping 30dB of gain off of a standard 9v adapter thanks to our proprietary dual rail power supply that boosts the internal voltage to +/-18v for 36 volts of headroom.


This industry leading headroom in a pedal allows the LIFT MKII the most clean gain on the market. It also means every nuance of your guitar and playing gets preserved with absolute fidelity.


Harmonic Drive

The Harmonic Drive is a highly praised circuit from our now retired hand-wired PreDrive and uses a unique combo of MOSFET and NOS D9E germanium diodes. The original Harmonic Drive was to our knowledge the world’s first discrete opamp based overdrive and the LIFT MKII starts where the V1 left off.


The Harmonic Drive is perfect for setting base tone and cleans up very well with volume or pick attack. Full range and zero compromise audiophile signal path means this is an overdrive unlike anything you have played before.


Passive, Studio-Grade Filters

We further refined the passive HIGH cut and LOW cut controls, which sweep from the outer edges of the audible frequency range for exceptional tone shaping.

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.


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.
