The normal "clean boost" mode is simply +25db of clean boost perfect to send your amp (or other effects) into overdrive. Use it to boost solo's and riff's, or to give your other dirt pedals more of an edge. Most clean boosts are designed to avoid what some call "ugly clipping" (that point where at the attack of each note, the signal is overdriven just enough to create distortion). Well, the clipping boost mode is designed with this artifact kept intact for a wonderful lo-fi overdrive sound. The Sucka Punch is two Punch loves in one.
