The J. Rockett .45 Caliber overdrive pedal is a boutique pedal designed to recreate the classic British-inspired crunch and feel of a 1962 Marshall JTM45, the iconic tube amp voiced for rock and blues tones. It delivers brilliantly crunchy rhythm tones and a wide gain range that can go from gritty breakup to face-melting roar while still remaining responsive and musical, with simple Loud (volume), Gain, Bass, and Treble controls for straightforward tone shaping. True bypass switching preserves your core tone when the pedal is off.
What sets the .45 Caliber apart is its explicit inspiration from legendary guitar sounds: the pedal’s creator cited AC/DC’s Malcolm Young and his signature crunchy rhythm tones as a sonic target, as well as Pete Townshend’s aggressive, dynamic sound on Live at Leeds as examples of the high-energy rock edge the design seeks to capture. After extensive development, J. Rockett aimed to nail not just the tone but the feel of those classic rock sounds in a compact pedal. In short, the .45 Caliber is built for players chasing vintage “stack-like” overdrive with a rock pedigree—especially fans of classic rhythm grit and expressive lead drive rooted in the sounds of Young and Townshend.
