A cab—short for cabinet—is the speaker enclosure that projects your guitar amp’s sound to the room. Cabs come in various sizes and speaker configurations, like 1×12, 2×12, or the classic 4×12 setup popular in rock and metal. The type of wood, construction (open or closed back), and speaker choice all influence the tone, response, and volume. Matching the right cab with your amp head is key to shaping your overall sound, whether you want tight, punchy lows, smooth mids, or bright, cutting highs. It’s where your amp’s power turns into the rich, full sound you hear on stage or in the studio.
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.
