Featuring three footswitches with sections such as synth, filter and delay, a built-in volume/wah pedal and COSM amp modeling technology plus compressor/limiter, the Boss ME-50B Bass Multi-Effect is built with virtually every effect a bassist could want in one package. Capable of summoning the sounds of Boss favorites such as the Slow Gear and Defretter while serving up live staples with ease, the ME-50B is a great place to look for anyone interested in doing away with their pedalboard.
