Discover the Marshall JCM800 Modified, inspired by the legendary JCM800 that shaped rock and metal. Honouring its iconic status as the amp of choice for bands like AC/DC and The Ramones, this version embraces the rich culture of modded Marshall amps while adding modern features for today's players. This modified iteration of the JCM800 delivers unparalleled tonal flexibility and features a gain boost, mid-boost, and tight switch so you can craft the perfect sound for any genre. From warm, smooth breakups to high-gain roars, capture the classic JCM800 tone with added features designed for the guitarists of today.

Features:

The mid-boost switch enhances mid-range frequencies, giving your tone extra warmth, depth, and clarity 
The tight switch is expertly designed to cut low frequencies to produce a clearer, more focused sound 

Inspired by guitarists, created by Marshall
The JCM800 Modified’s design is a celebration of musicians and gear enthusiasts who customise their amps. We’ve revamped the iconic JCM800 with modern features that help you carve out powerful tones.
