Tempo can be easily adjusted with the tap tempo function, and one small switch allows changing time division between 1, 2 and 4, so the tap rate can be matched one-to-one, doubled, or quadrupled. There's a volume, a speed knob if you prefer to set speed that way, and a 'duty' knob which controls how much gap there is between each tremolo cycle.
The delta knob controls how much the tremolo speeds up or slows down once it kicks in - you can make some truly amazing, ethereal and weird sounds with this function. While it takes a little getting used to, play around with this dial and you'll soon discover this pedal has tons of expressive depth.
Engineered by the best in the business, and individually hand-painted, this is a pedal that will allow you to find a sound that fits you.
