A boost pedal is used to increase the overall volume or gain of an instrument’s signal, typically without adding distortion or altering the tone drastically. It’s commonly used to push the amp into overdrive, making solos stand out or increasing the power of the signal for a more pronounced sound. Boost pedals can also be used to emphasise specific frequencies, helping the instrument cut through the mix during performances.

There are different types of boost pedals, such as clean boost and colored boost. Clean boost preserves the natural tone of the instrument while increasing the volume, whereas colored boost can alter the sound slightly, adding warmth, presence, or a subtle tonal shift. Popular boost pedals include models from Xotic, Electro-Harmonix, and TC Electronic, each offering different features like EQ controls, low noise, and transparency, allowing players to tailor their boost to fit their unique playing style.
