This all-analog pedal gets its voice from MOSFETs, or metal–oxide–semiconductor field-effect transistors. This is a fancy way of obtaining distortion, as opposed to the cheaper LED or germanium diodes. This provides a more dynamic and wide-ranging distortion sound which retains its clarity and punch throughout the distortion range. The focus was on a great sound on all levels of drive, and not just when it is full up. The end result is that it acts more like an amp than a typical distortion pedal- it has that feel that is so difficult to get out of something the size of a pedal. It can be used with a 9v battery or power supply but it can also be powered at 18v for increased clarity and crunch. • MFSKU 11900-001 • UPC 800315039678
