This pedal has a smooth vintage shape and warm tone. The Speed will take you from a very slow pulse to a fast one with an extremely smooth transition. The Depth starts out subtle and moves all the way up to a rowdy full cut off. You will have to learn to play the pedal in the top setting. The volume control at 12 o'clock is at unity higher up it will compress your sound giving it better tracking. Unlike most vintage Tremolos it retains it sparkling Mids and Highs.
