Ambient Delay

The Expression Series Ambient Delay provides a hybrid of digital delay layered with plate reverb, for everything from slap-back to extended repeats. It features settings for delay time (50ms - 1s), delay feedback, reverb level, and a foot-sweepable effect level control to create anything from subtle textures to ambient soundscapes, all without taking your hands off the guitar.
