When you start talking about Distortion and Overdrive pedals, it's important to remember the differences between the two. Overdrive pedals achieve their effect by exploiting the gain of an audio signal. The lower the gain, the warmer and more subtle it is. The higher the gain, the more drastic it is. Distortion, on the other hand, impacts low and high gain signals equally by clipping the peaks of the signal's sine wave regardless of volume level. The CNZ GDS-20 is a great workhorse distortion pedal. It gives you Level, Gain, and Tone controls while also letting you choose between 3 types of distortion via a toggle-switch. All of it fits in our standard "mini" case. Whether you like your distortion subtle and dark or obvious and bright, you'll love this pedal.
