J. Rockett .45 Caliber


Add to Cart

The J. Rockett Audio Designs .45 Caliber overdrive is a smoking hot "amp-in-a-box" pedal designed to emulate the sound of a cranked JTM45. A simple control layout with two-band EQ, gain and output get you a range of tones that absolutely nail what you hear on an AC/DC record. Take this thing into a vanilla-sounding clean tube amp and send it on a highway to hell in a hurry.
It’s hard to re-create the experience of plugging into a dimed British amp head, but that’s exactly what the .45 Caliber overdrive seeks to do. A surprisingly versatile gain range and powerful Bass and Treble shaping controls have what it takes to transform your clean combo into a face-melting stack. Dialing back the gain and output yields a nuanced bluesy breakup, with a responsive spank and sag that even veteran lead players will recognize immediately.
