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.

Amps

Guitar amps cover everything needed to amplify, shape, and project your guitar sound, from small practice setups to full stage and studio rigs. In this category you’ll find combo amps, separate amp heads and speaker cabinets, covering valve, solid-state, and hybrid designs, each offering a different feel and response. You’ll also see modelling and digital amps, built-in effects, footswitches, attenuation solutions, replacement speakers, valves, and essential accessories to keep an amp performing at its best. Whether you’re chasing pristine cleans, classic crunch, or modern high-gain tones, guitar amps and related gear are all about finding the right balance of power, tone, and control for the way you play.
