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.

Module

Preamp

A preamp (preamplifier) is the first stage in your guitar signal chain that takes the weak signal from your guitar and boosts it to a usable level for shaping tone and driving the power amp.

It’s where much of your tone is formed—controlling gain, EQ, and character. In valve (tube) amps, the preamp stage is what gives you that classic warmth and breakup when pushed. In modern rigs, standalone preamp pedals or rack units can mimic classic amp tones or create entirely new ones. Whether in a studio or live setup, a good preamp is the heart of your sound.
