Boss is a manufacturer of effects pedals for electric guitar and bass guitar. It is a division of Roland, a Japanese manufacturer that specializes in musical equipment and accessories. For many years Boss manufactured a range of products related to effects processing for guitars, including "compact" and "twin" effects pedals, multi-effect pedals, electronic tuners and pedal boards. In more recent times, Boss expanded their products line to include Digital Studios, rhythm machines and other electronic equipment.
All Boss compact pedals use "buffered bypass" utilizing JFET transistors to avoid clicks and pops. While not "true" bypass, the buffered bypass has the advantage of preventing signal loss due to long runs of cable, while keeping original guitar tone intact.
