Electro-Harmonix Memory Boy Delay Guitar Effects Pedal The Electro-Harmonix Memory Boy is a smooth analog delay that takes its heritage from the 1970s Memory Man and the legendary Deluxe Memory Man. The Memory Boy uses the Deluxe Memory Man as a base, expanding upon it with additional modulation features and an optional expression pedal input for external control over delay time or modulation rate. Memory Boy features a 550ms delay time, allowing you to explore limitless textures. A three-way toggle switch lets you add in vibrato or chorus, or control the delay time with an external expression pedal. Since the early 1970's, Electro-Harmonix has been designing analog delays featured on some of the greatest recordings and used by iconic musicians throughout the world. From the original Memory Man guitar pedal to the Deluxe Memory Man, still available today, EHX delay pedals are desired instruments for the organic tones that deliver textures that define quality.
