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 Overdrive delivers natural tube-like overdrive with more range than ever before. It features settings for drive, boost and tone, with a foot-sweepable overdrive control, making it effortless to go from clean to searing lead tones and everything in between, without having to take your hands off the guitar. 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
