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.
Overdrive is a type of guitar effect that simulates the natural distortion that occurs when a tube amplifier is pushed beyond its clean limit. Overdrive pedals achieve this by boosting the input signal of the guitar, causing the amplifier to saturate and produce a warm, saturated, and crunchy sound.
Overdrive pedals are commonly used in various styles of music, including rock, blues, and punk, to add grit, sustain, and harmonic richness to the guitar’s sound. They are versatile tools that can be used to achieve a wide range of tones, from subtle breakup to full-on distortion, depending on the settings and the amplifier being used. Some classic examples of overdrive pedals include the Ibanez Tube Screamer, the Boss OD-1, and the Fulltone OCD, among others
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.
Tube refers to vacuum tube technology used in guitar amplifiers to amplify the signal. Tube amps are celebrated for their warm, rich, and dynamic tone, producing natural overdrive and smooth distortion when pushed. They respond sensitively to a player’s touch and playing style, offering expressive sound shaping that many musicians prefer. Although tube amps require more care and maintenance than solid-state models, their classic sound and feel keep them popular among guitarists worldwide.
