The Axe Grinder has been designed with a couple of key fetures in mind, it not only allows a wide variety of distortion tones from the clipping part of the effect it also allows the user to overload thier amp with a greatly boosted clean tone. The distorted tone and the clean tone can be blended together for additional sound tailoring. Also the tone control only affects the distorted signal, and leaves the clean signal untouched. The "cancel" switch lets your guitar signal bypass the effect entirely.
