Single Gain Control
A lot of boost pedals these days are filled with a bunch of unnecessary controls that are not really needed for day to day use. So with this simpler single control setup you can get a pure clean volume boost that depending on your amp will push it slightly dirty or just give you a nice boost in volume for the next time you want to go into a sweet new solo.
Fat And Bright Switches
Having a bright switch is a must on any boost pedal as it gives you that extra bit of bite you would want when going in to a solo. The Fat switch is really interesting and is not something you see everyday on a small boost like this. With this you can adjust the low end response of the amplifier so if you find your sound becoming a bit thin with the boost engaged you can fatten it up with just a flick of a switch.
At the end of the day it is your pedal and you want it to sound great no matter what amp or guitar you are using and these switches mean it does just that.
