The Coal Dust Boost is a true bypass, mosfet based clean boost that proves useful in many situations. With +30dB of boost, there is plenty of gain for boosting solos or goosing the front end of an amp or pedal for more drive. Volume attenuation is available on the low end of the dial, with unity around noon, and beautiful boost throughout the rest of the rotation. As an "always on" pedal, it eliminates high end roll off that occurs from long cable runs or multiple pedals. It does a great job of adding strength, clarity and sparkle to a clean sound, without completely altering your tone. The Coal Dust Boost adds a little something special to your sound, while giving you just a bit more of what you already love.
