The key to the power of the Alesis MicroVerb 4 is in its simplicity. It offers 200 programs that include everything from high-quality reverb, delay, chorus and flange to exciting multi-effects and more. To customize your programs, 2 front panel knobs allow for quick, easy, user-storable edits, or use its MIDI inputs for control over program changes and modulation. You can then save your edited programs in the 100-space user program bank. Even though its affordable and easy to use, the MicroVerb4 offers the superb audio quality that you should expect from every Alesis processor.
