About the manufacturer

Marshall

Marshall is a legendary British amplifier brand that defined the sound of rock music with its unmistakable power, grit, and presence. Founded by Jim Marshall in London in 1962, the company quickly became synonymous with the roaring tones of the 1960s and 70s, used by icons like Jimi Hendrix, Pete Townshend, and Slash. Known for their iconic “stack” design and warm overdrive, Marshall amps deliver the punchy, dynamic sound that has powered countless stages and recordings. From classic valve amplifiers to modern digital models, Marshall continues to embody the spirit of rock’n’roll—loud, bold, and timeless.

Amp Heads

An amp head contains the core tone and power of a guitar amplifier without the built-in speakers, allowing you to pair it with the cabinet of your choice. This setup offers greater flexibility over sound and volume, as different speaker cabinets can dramatically change the feel and character of the amp. Amp heads are available in valve, solid-state, and hybrid designs, ranging from low-wattage studio models to high-powered touring rigs. They’re ideal for players who want a modular setup, precise control over their tone, and the ability to adapt their rig to different venues, cabinets, or recording situations.
