FAQ
A combo guitar amp combines the amplifier electronics and speaker in one cabinet. It differs from an amp head, which typically connects to a separate speaker cabinet. Combo amps are available for electric and acoustic-electric guitars.
Solid-state guitar amps use transistors in their amplification circuits, while tube amps use vacuum tubes. Tube amps are often associated with natural overdrive, while solid-state models may offer clean and distorted channels. Some hybrid amps combine tube and solid-state circuitry.
A modeling guitar amp uses digital processing to recreate the sounds of different amplifiers and, on some models, speaker cabinets. Many also include effects such as reverb, delay, and chorus. Presets store combinations of amp sounds and effects for later use.
Gain controls the signal level entering the preamp and often affects the amount of distortion, while volume controls the output level. Bass, middle, and treble adjust different frequency ranges. Depending on the amp, additional controls may adjust reverb, select channels, or choose built-in effects.
Beginner guitar amps typically have a 1/4-inch instrument input for a guitar cable. Depending on the model, other connections may include a headphone output, an auxiliary input for backing tracks, or a USB port for recording or editing presets. Some amps also offer Bluetooth audio playback, which is separate from the wired guitar input.
