You are looking at the electro-harmonix Memory Toy.

The electro-harmonix Memory Toy effects pedal is a pure analog delay with up to 550ms of delay. It is also produces a chorus effect. 

Delay controls the delay time of the EHX Memory Toy guitar pedal and the range of delay time is from 30ms to 550ms. Turn the delay time clockwise to increase the delay amount. The Blend control allows you to vary the mix of direct and delayed signals from 100% dry when set counterclockwise to 100% wet at full clockwise. The effect pedal's feedback control increases the number of delay repeats or multiple echoes. At high settings the unit will begin to self-oscillate. Fairly high feedback with short delay settings produces a reverb type of effect. The Mod switch will enable a slow modulation on the delay time similar to the chorus modulation of the Deluxe Memory Man. The Status LED shows that the electro-harmonix Memory Toy is in effect mode. When the LED is off, the Memory Toy is in true bypass mode. Use the footswitch to toggle between the two modes.
