Positive Grid Spark Edge Portable 4-channel 65W Smart Amp & PA – £399 New

Amp

An amp, short for amplifier, is a crucial piece of equipment that boosts the signal from your guitar or other instruments, allowing you to control volume and shape your tone. Guitar amps come in various styles, including valve (tube), solid-state, and digital modelling, each offering unique sound characteristics. Whether you’re practicing at home, recording in the studio, or playing live, the right amp can make all the difference in achieving your desired sound—from clean and crisp to rich overdrive and distortion.

Guitar Amps and Cabs

Guitar amps and cabs are just as crucial to a guitarist’s tone as the guitar itself. Amplifiers shape the sound—whether it’s clean and warm, crunchy and bluesy, or full-on distortion for rock and metal. They come in two main types: combo amps, which include both the amp and speaker in one unit, and amp heads, which are paired with separate cabinets (cabs) to project the sound.

Cabs come in various sizes, like 1×12, 2×12, or the mighty 4×12, each delivering different tone and feel. Speakers, cabinet wood, and even open vs closed backs all influence the sound. Matching the right amp and cab gives players control over their dynamics, tone, and presence—whether you’re playing in your bedroom, a studio, or on a festival stage.
