BOSS OS-2 OverDrive/Distortion Pedal.
The OS-2 gives players a choice of overdrive or distortion or lets them combine both – all in a single compact pedal. Its distortion maintains the subtle nuances of single-coil guitar pickups.
• Flexible distortion pedal capable of producing blended overdrive/distortion sounds
• Provides both over-the-top distortion sounds and less extreme overdrive tones for rhythm playing
• Includes Level, Tone, Drive and Color controls for precise tonal shaping
Boss is a manufacturer of effects pedals for electric guitar and bass guitar. It is a division of the Roland Corporation, a Japanese manufacturer that specializes in musical equipment and accessories. For many years Boss has manufactured a wide 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 product range by including digital studios, rhythm machines, samplers and other electronic music equipment. They also are now manufacturing solid-state amplifiers and speaker heads such as the Waza and the Katana. Both feature multi-effects units meant to emulate Boss' classic effects pedals.
