The Pigtronix Class A Boost will fatten up and boost anything you feed it. Our 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 ships with an 18 volt adapter for superior headroom and maximum punch. Make your sound 1 louder with this handsomely dressed, J-FET masterpiece from Pigtronix.

Comments about Pigtronix Class A Boost Pedal:

The perfect clean boost pedal! Simple straight forward and down right awesome! Perfect for injecting a little or a lot of clean clear boosted signal into your amp this little monster has up to 20db of signal to deliver. Perfect for "punching your amp in the face!" This pedal will not color your sound or overcomplicate things with multiple knobs and EQ's. You may just keep it on all the time and it might even replace some or all of your "Screamer" style pedals. The pedal is handmade in the USA, comes with a power supply and is also true bypass.
It does not get any better than this
