Pigtronix Class A Boost Pedal

Some things just work. They do exactly what you expect them to do, no more, no less – and that’s a good thing. The Class A Boost from Pigtronix is one of those things.

The concept sounds simple. I wanted a pedal that will give me a nice volume boost when I stomped on it and not drastically change my tone. It’s the latter part of the concept where most boost pedals fall short. While you would have to have some reasonable expectations of a difference in tone when volume is increased, most boost pedals I had tested seemed to add too much coloration on their own and that’s why I was totally impressed by the Class A Boost.

Pigtronix got this right by using discreet transistors in a “class A” configuration which delivers a clean, warm tone all the way through the maximum 20db – yes, 20db – of boost. When you engage the Class A Boost, you will get noticed, even if it is just a subtle bump in volume or if you want to drive your tube amp a bit harder, the Pigtronix comes through as expected.

Simplicity personified, there is only one knob (gain) on the Class A Boost and the pedal has the excellent build quality we’ve come to expect from Pigtronix. It turns on a 9-volt, but includes an 18-volt adapter which the manufacturer states will deliver superior headroom and maximum punch.

I was thrilled to find a boost pedal that finally did exactly what it was suppose to do. After playing around with the Class A Boost I discovered that it performed really well anywhere in your effects chain – and played really well with other pedals in my rig. Did you ever get a really great sound out of a distortion pedal, but lost it when you had to crank up the gain knob? Throw the Pigtronix Class A in front and let it rock!

Bottom line: The Pigtronix Class A Boost is a solid performer that not only does what it is suppose to do but can bring out the best in your amp and existing effects.
