  BOSS is a company known for manufacturing guitar and bass multi effects pedals. It is considered to be one of the top comapnies on the market, and its effects are used by many top selling artists such as Aerosmith, Victor Wooten and The Eagles. BOSS has been producing musical effects since 1976 when it created the B100 pedal to amplify acoustic guitars.
  
  

GT-10B

• The GT-10B bass effects processor, as of 2010, is BOSS's top of the line bass multi effect pedal. This pedal is optimized to work with low end sound, and provides bassists with effects such as over drive, sustain and delay. This pedal can also be used as a looping station to allow more diversity while playing.
  
  

ME-50B

• The ME-50B is BOSS's more affordable bass multi effects pedal. While not quite as diverse as the GT-10B, the ME-50B still provides bassists with a multitude of effects. This pedal features a compressor, over drive, delay and a wah pedal. The ME-50B also comes built into a rugged steel casing to protect it from damage while being used.
  
  

ME-20B

• The ME-20B is BOSS's multi effects unit meant for the beginning bass player. This is the most stripped down effects pedal for bass that BOSS offers. It features effects such as over drive, flanger, phaser and reverb. It also comes with a built in wah pedal. This unit is battery operated to provide mobility during live performances.
