Launched at NAMM 2009, the Boss ME-70 took the world of multi-effects units to the next level with its COSM modeling technology and phrase sampling ability. Today, it still stands its ground as one of the easiest-to-use multi-effect floor units, with familiar Boss controls and parameters and tons of classic amp models and Boss pedals built in. If you don't want to spend a fortune to amass a diverse pedal collection or lug around a huge board, this is the answer.
