Coal Dust Boost

​The Coal Dust is a true bypass Class A boost based around the classic cascading JFET Mu-amp design. This version has the bias adjusted to be "on the verge of breakup" so that with normal playing the boost is cleaner and powerful, but when you really dig in with your pick, you start to get a hint of grit similar to how a tube amp would react with mild musical compression. You can make this a cleaner boost, or a gritty boost by adjusting the internal trim pot that controls the bias of one of the transistors. This makes it a perfect match for a variety of applications. With +20dB of boost, there is plenty of gain for boosting solos. As an "always on" pedal, it eliminates high end roll off that occurs from long cable runs or multiple pedals. The Coal Dust Boost adds strength, clarity and sustain and does a great job punching the front end of an amp or a drive pedal. ​
