Overview of the Boss Pedal Company

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.

The earliest Boss product was B-100 The Boss, released in 1974. This came with a clip-on pre-amp and a pickup to amplify acoustic guitars. At this point, existed as a Beckmen Musical Instruments product (as seen on the B-100 box). The first proper Boss foot pedal effect, the CE-1 Chorus Ensemble, released in June 1976, encompassed a stand-alone unit of the chorus/vibrato circuit found in the Roland JC-120 amplifier. It was a fairly large, AC-powered unit. Other foot pedals of that year are the GE-10 (a graphic equalizer), the BF-1 (a flanger unit), and the DB-5 (a distortion unit).
