Grunt Switch

Attack Switch
Sets the amount of treble content to saturate: The "Boost" setting emphasizes the treble content extra clarity and presence. The "Flat" position leaves this register untouched while the "Cut" position will reduce the amount of high frequencies being saturated.This new addition helps to keep the treble portion of the signal under control, specially useful when playing with new strings and/or cabinets with tweeters!
