Stuff About 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.
