Legendary Tones

Caswell 1987 Mod 

Standard Wire Version

Overdrive Guitars are the official UK dealer for Legendary Tones products.

In 1987, rock guitar hit its most aggressive and unapologetic peak. Big stages, loud amps, and tones that cut through the mix with authority. At the centre of it all was Tim Caswell’s legendary #39 mod—a modified Marshall circuit that delivered raw gain, rich harmonics, and a voice that defined an era.

The Caswell 1987 Mod brings that iconic sound back to life.

Inspired by the original #39, this mod captures the aggressive gain structure, touch sensitivity, and harmonic complexity that made it famous, while refining the design for modern players and modern rigs. Built on the proven foundation of the Hot Mod V2, it stays true to the spirit of late-’80s excess while offering greater control and consistency.

Expect explosive attack, tight low end, glassy upper harmonics, and that unmistakable LA Strip grind that jumps out of the mix. Whether you’re chasing the tones of your heroes or carving out your own signature sound, the Caswell 1987 Mod delivers the perfect balance of clarity and controlled chaos.

Controls & Features

Drive Control

A fully variable Drive control lets you dial in anything from classic, tight crunch to saturated, singing lead tones. Total command over gain, sustain, and aggression.

Thump Switch

Engage the Thump switch for a powerful low-end boost that adds weight, punch, and authority. Perfect for palm-muted riffs and big arena-style power chords.

Bite Switch

The Bite switch enhances upper-mid harmonics and presence, adding edge, articulation, and cut. Solos leap forward with classic ’80s studio sizzle and clarity.

The Caswell 1987 Mod delivers the sound of a defining moment in rock history—reborn with modern reliability, control, and zero permanent modification. If you want the tone of 1987 under your fingers, this is it.

Please view the full list of compatibility so you know which version (standard or reverse-wired) to choose before placing your order. Certain amps will require socket extenders (e.g. Mesa Badlander, Marshall DSL, etc.) and we now include these with all orders.

Get in touch if you're unsure whether this will work with your amp.
