Cusack Music Tap A Delay
Here’s a ProGuitarShop video of the Cusack Music Tap-A-Delay.

From the manufacturer’s website:

The Tap-A-Delay is a 750mS digital delay that mixes the original analog signal with the delayed signal. It is gritty and a bit noisy and very analog sounding. This isn’t your clean studio quality digital delay with perfect repeats. – More info here.
