The Gladio SC is based on the legendary tone of guitarist Stevie Ray Vaughan. Capturing similar sounds of the original Gladio but adding a clean control to dial in as much or little of your clean tone along with the gain! This drive pedal is perfect for shaping lead and rhythm tones. Put it before a clean amp, or driven, stack it with delay, chorus, or more gain! Cornerstone pedals are made for the professional guitarist.
