Electro-Harmonix - Memory Man 550-TT

550 stands for its maximum delay time in milliseconds and that's the same spec as the classic Deluxe Memory Man. Tap Tempo guarantees you're always in sync with the groove, wherever a performance (or your rhythm section) takes you. Five Tap Divide subdivisions deliver rhythmic variation while an Expression Pedal input provides real-time player control over Blend, Rate, Depth, Feedback and Delay. The FX Loop lets you insert effects into your wet signal without changing your dry signal.
