Buying Guide

Decide between headphone or speaker amp

Headphone amps like compact plug-in units are ideal for quiet practice and portability, while small speaker combos provide room sound and simple EQ controls

Check power and intended use

Lower-watt amps (single-digit to ~10W) are fine for bedroom practice; higher wattage matters only if you need louder room projection

Look for useful onboard features

Basic effects (reverb, basic amp voicings) and a playable EQ let you shape tone without extra gear—handy in compact units

Prioritize output options

A dedicated headphone jack supports silent practice and recording; line outputs or AUX inputs add flexibility for backing tracks

Consider build quality and brand support

Established brands often offer more consistent component quality and documentation, which helps with longevity and setup
