The Orange Crush started out as a custom pedal that had been used for quite a few years by Greer Amplification endorsers. It was put into production after word got out that certain endorsers had this custom pedal and people started asking Nick to make it available to them, too. It's a simple pedal that has the same tone as the Black Fuzz circuit with the added feature of the tone knob. The tone knob is a full range tone knob that, when turned full left, cuts the highs and gives the user a thick, bassy fuzz tone and slightly smoothes the fuzz. When full right, the tone knob gives the user lots of treble and in between sounds--very balanced and pleasing. Plug in, turn up, live loud!
