The Electro-Harmonix Deluxe Memory Man 1100-TT Analog Delay with Tap Tempo Guitar Pedal features expression control and an effects loop. For decades, the Deluxe Memory Man has been the industry bottom line for sweet organic delay and modulation. Prized by serious musicians, the Deluxe Memory Man became the definition of attitude and character that still leads the way to analog perfection. Ultimate Delay Control Electro-Harmonix has created the ultimate Deluxe Memory Man equipped with Tap Tempo, 1100mS of maximum delay time, Expression Control, and an Effects Loop. Adding Tap Tempo ensures that you will always be in sync with the groove, wherever your performance takes you, while five Tap Divide subdivisions deliver rhythmic variation. The Expression Pedal Input provides real-time control over Blend, Rate, Depth, Feedback, and Delay. The Effects Loop lets you insert effects into your wet signal without changing your dry signal, making the EHX Deluxe Memory Man 1100-TT the most powerful analog delay ever designed. Blend Knob The Blend knob is a wet or dry control allowing you to vary the mix between direct and delayed signals at the Output jack of the 1100-TT. Gain Knob Sets the input gain for the 1100-TT. Rate Knob The Rate knob’s main function is to set the rate or speed of modulation. Depth Knob Sets the amount of modulation that is applied to the delay time. Feedback Knob Controls the amount of signal that is circulated from the output of the delay block to its input. Delay Knob Sets the delay time from 52 to 1100ms. Input Jack Connect the output of your instrument or other effects pedal to the 1/4-inch Input jack. Send Jack Connect this jack to the input of another effects pedal or chain of effects pedals to insert an effects loop before the 1100-TT’s delay block. EXP Pedal Jack Enables the musician to control any of the five available expression modes with an optional expression pedal or control voltage. Tap SW Jack Allows the musician to input the tap tempo from an external momentary switch. Return Jack Connect this jack to the output of another effects pedal or chain of effects pedals to insert an effects loop before the 1100-TT’s delay block.
