LIFT MKII

Buffer/Boost Preamp Guitar Pedal

The Pettyjohn LIFT MKII operates as an always-on preamp pedal for guitar or bass, switchable between Buffer and Boost modes.

Product Overview

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

 

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

New Features

  • Discrete opamp always-on unity gain buffer.
  • Discrete opamp powered boost with up to 30 dB of clean gain.
  • Studio grade EQ with transparent, wide-range high cut and low cut filters.
  • Harmonic drive features a NOS D9E germanium diode.
  • Harmonic Drive with blend pot for wide range of tones.
  • Low filter can be assigned to always on or boost only.
  • Extended full range frequency response: 20Hz-25kHz (EQ off).
  • Adjust output Level to allow for driving the harmonic drive circuit hard.
  • High performance proprietary dual-rail power section providing 36V of voltage swing for huge internal headroom off a 9v adaptor while drawing under 200mA (draws 150mA off of 15v adapter).
  • The foot switch has been updated from a poppy 4PDT switch to a soft touch, relay based system.

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.

A Better 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.

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.

 

The Lows control sweeps from 30Hz to 1.5kHz with a gentle, musical 6 db per octave slope. This control can be internally assigned to be always-on with the buffer or to activate only in Boost mode and ships in Boost mode configuration.

 

The Highs takes care of shaping the top end with a transparent WIMA cap from 22kHz to 1kHz. The Highs filter is only active in Boost mode. You can upgrade the WIMA cap to a more vintage Orange Drop cap for a more colored, warmer top end.

Return Of The Harmonic Drive

When engaged with the toggle switch labeled ON or OFF the Harmonic Drive circuit can be blended into the Boost mode via the Drive mini pot. This gives the LIFT MKII the powerful ability to go from pristine cleans to harmonically excited boost to an all out overdrive.

 

The Harmonic Drive is a highly praised circuit from our 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.

 

With three times the gain on tap, you can push the Harmonic Drive circuit into full saturation. The harmonic drive clipping circuit is a unique among overdrives and characterized by a sweet, natural compression and harmonically rich, organic growl that doesn’t break or buzz like most overdrives on the market.

 

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.

The Original Studio Grade

At Pettyjohn we build true studio-grade pedals. No, this isn't some cheeky marketing jargon; we accomplish extremely low signal noise with carefully selected top-shelf components:

 

  • Audiophile grade, through-hole 1% metal film resistors.
  • 
Top-shelf WIMA and Silver Mica caps used in tone sensitive operations.
  • Lead-Free PCB constructed with Audiophile lead-free silver solder
