Dave Koltai, Pigtronix founder, came to our shop in CT when he first decided to make effects pedals, and showed us his original Envelope Phaser. We gave him our opinion and some hints and I think we were his first dealer. We are the only dealer who still has those original EP-1 pedals, as he showed us how to calibrate them and get them working well.
The Pigtronix Class A Boost will fatten up and boost anything you feed it. The 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.
