I have had all the overdrives including most of the Barbers. I purchased used this time because I was sick of losing money selling pedals. This pedal kills and I really mean kills. It does low or high gain and is very, very amp like in some of the settings. You can dial in low to medium gain that is absoultely flooring me. I am very, very surprised. This was to be my last pedal and I was going to call it quits with overdrive pedals. Man this pedal is going to go down in history as one of the best! WOW!!!!!!
