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.

150W

Products with the 150W tag have an amplifier or power stage whose stated output is 150 watts. Wattage alone does not determine perceived loudness, clean headroom or suitability for a room: speaker efficiency, impedance, cabinet design, amplifier type and how the power is measured also matter. Compare the complete specification and intended practice, recording or performance use.

1×12

1×12 refers to a speaker configuration with one 12-inch speaker, most commonly found in guitar amplifiers and speaker cabinets. It offers a balanced combination of clarity, low-end response, and projection, making it a versatile choice for both home use and live performance.

Compared to smaller speaker setups, a 1×12 delivers a fuller sound with more body, while remaining more compact and portable than larger multi-speaker cabinets. It is popular with players who want strong tone and punch without the weight and volume of a 2×12 or 4×12 setup.

Amp

An amp is an amplifier used to boost the signal from a guitar and shape its overall tone and volume. It plays a major role in how a guitar sounds, influencing everything from clean clarity to natural overdrive and distortion, and is a core part of any guitar setup for both practice and live performance.

Combo Amp

A combo amplifier combines the amp head and speaker cabinet into one convenient, self-contained unit, making it a favourite for players who want great tone without extra setup. Compact and portable, combos come in all sizes and power levels, from small practice amps to stage-ready tube beasts. They deliver everything from sparkling cleans to rich overdrive, often with built-in effects and tone-shaping controls. Perfect for rehearsals, recording, or gigs, a good combo amp gives you the full sound and feel of a complete rig in one easy-to-carry package.
