The Pigtronix Class A Boost will fatten up and boost anything you feed it. Its deceptively simple design uses discreet transistors in a single-ended "Class A" configuration to achieve the warmest possible tone. This remarkable preamp can deliver up to 20dB of clean boost and remains effective with both instrument and line-level signals.

Superior signal-to-noise performance allows you to put the Class A Boost anywhere in your pedal chain. It can add punch and extra output to a classic overdrive sound and is able to push distortion pedals into extremely aggressive crunch land. Class A Boost is also ideal for hitting the front end of a tube amp to achieve an added layer of sweetness and fat tone.

This pedal runs fine on 9 volts but works with an 18-volt adapter (sold separately) for superior headroom and maximum punch. Make your sound one louder with this handsomely dressed, J-FET masterpiece from Pigtronix.
