Small Clean Boost
The Pigtronix Class A Boost will fatten up and boost anything you feed it. This deceptively simple design uses discreet J-FET transistors in a single-ended “Class A” configuration to achieve the warmest possible tone. The Class A Boost can deliver up to 20db of clean boost and remains effective with both instrument and line level signals.
