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.

Bass

Bass gear is all about laying the foundation of the music, providing depth, groove and connection between rhythm and harmony. From bass guitars and amplifiers to pedals and accessories designed specifically for low frequencies, everything here is built to deliver clarity, punch and control. Whether you are holding down a steady rhythm or shaping a more melodic bass voice, the right bass equipment helps you stay locked in and felt as much as heard.

Guitar Amp Head

Guitar amp heads contain the main tone-shaping and power section of an amplifier, designed to be paired with a separate speaker cabinet. They let you choose different cabinets to suit your sound and setup, offering flexibility for home, studio or live use. If you want control over volume, tone and character without being tied to a single combo format, amp heads give you a modular way to build the rig that works best for you.

Tube

Tube refers to valve-based amplification or circuitry that uses vacuum tubes to amplify the guitar signal. Tube amps and tube-driven pedals are valued for their warm tone, natural compression, and smooth overdrive, responding dynamically to playing strength and volume changes for a more expressive feel.
