Ernie Ball is one of the world’s leading manufacturer of strings and accessories and has been making high-quality electric guitar and bass strings since 1962. Using the latest technologies and finest materials to continuously improve and enhance their products, Ernie Ball also offers a high-quality range of merchandise and accessories and effects.

The Ernie Ball Expression series pedals feature some of today's most popular effects housed in a rugged compact volume pedal format. 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. This gives you far more expressive possibilities than traditional on/off stompboxes. Like the Ernie Ball volume pedals, Expression Series pedals are housed in an aircraft grade aluminium chassis that is practically indestructible
