This pedal is in excellent condition, comes boxed with user manual and power supply. The Akai Prfessional E2 Head Rush as used by KT Tunstall ,combines delay,tape echo,and a looping recorder. The pedal simulates a four Head analog tape machine, in looping recorder mode it enables you to overdub layer after layer of sound in real time making it a great live performance tool. In delay mode it is infinitely adjustable. It has hardly been used and is a great pedal at a great price!
