EZ EDIT lets you create sounds quickly and intuitively, with incredible ease and speed like no other multi-effects unit on the market. You can adjust a combination of effect parameters with a single knob, and then save your creations for instant recall.
Up to 30 of the sounds you create can be stored in the ME-20B’s User memory. In Memory mode, you can use the pedals to instantly select a stored sound. Since the ME-20B makes it so easy to create new sounds, the user memory bank ensures that you’ll never lose those perfect patches.
