The down and dirty… it can do regular delays, modulated delays, or multitap delays… there are four banks of A/B presets…. And whichever preset you’re on, you can hold that button and trigger tap tempo… or hold the opposite button for infinite repeats to fade out of parts.
Most of them are black, but they made a few glow in the dark or red special editions. This white one with the graphic is apparently 1 of 100, but I just thought the color would look good on my pedal board.
