Pigtronix Class A Boost is a deceptively simple pedal that uses discrete J-FET transistors in a single-ended "Class A" configuration to achieve the warmest tone possible.

The Class A Boost can deliver up to 20dB of clean boost and remains effective with line-level and instrument signals.

With superior signal-to-noise performance, it allows you to place the Class A boost anywhere in your pedal chain. It can add punch and extra output to a classic overdrive sound and is capable of pushing distortion pedals into extremely aggressive crunch territory.

Class A Boost is also ideal for hitting the front end of a tube amplifier to achieve an additional layer of sweetness and thick tone.
