Boost

A boost guitar effect increases signal level without significantly altering tone, making it a simple but powerful tool for adding volume, clarity, or gain to a guitar rig. Boost pedals are commonly used to push an amplifier or overdrive pedal harder, resulting in more sustain, saturation, or presence. Unlike distortion or overdrive effects, a boost is designed to enhance what is already there rather than create a new tonal character.

Most boost pedals offer a single level control, though some include additional tone shaping options such as EQ or frequency emphasis. When placed before a gain stage, a boost increases input signal, driving the amp or pedal into heavier breakup. When placed later in the signal chain, it functions as a clean volume increase for solos or dynamic passages. This flexibility makes boost pedals useful in a wide range of setups and playing styles.

Boost effects are used across nearly every genre, from blues and rock to metal and country, because of their simplicity and effectiveness. They help solos cut through a mix, add definition to rhythm parts, and compensate for volume drops when switching guitars or effects. For guitarists looking to enhance dynamics and gain control with minimal complexity, a boost pedal is an essential and versatile addition to any pedalboard.
