The EchoTAP delay is a dual delay that offers two adjustable echoes in one pedal. The TAP Tempo can be set from 30ms to 3 seconds; the panel echo can be set from 50ms to 3 seconds and each echo have separate volume controls. This is a very useful tool on your pedal board allowing you to set a room type slap-back echo on the panel and punch over to a 'tapped' tempo long delay - on the fly. Other combinations can be set as desired.
