In 1987, the sound of rock changed forever. Raw, unapologetic and drenched in attitude. Tim Caswell’s infamous #39 mod turned a standard Marshall into a snarling, harmonically rich beast – the tone that fueled a generation of guitar heroes.
The Caswell 1987 Mod captures the heart and soul of that groundbreaking circuit: aggressive gain structure, sensitivity and harmonic fire. Built on the foundation of the acclaimed Hot Mod V2, it refines the formula for today’s player while staying true to the spirit of late-’80s excess. Expect explosive punch, glassy upper harmonics and that unmistakable “LA Strip” grind that jumps out of the mix. The sound of 1987, reborn.
