Multi-Effects Made Simple

BOSS understands that bass players want access to powerful effects, but they don’t want to get caught up in the menus and programming hassles of a multi-effects processor. Enter the ME-50B. Just like its guitar-oriented sibling, the new ME-50B puts BOSS’ finest multi-effects for bass into a convenient floor processor with the feel of a compact pedal. Forget about menus and cursor buttons. Just reach down and twist a knob!

Get Creative with Cool Filter/Tone Effects

The ME-50B includes a variety of unique tone-shaping effects just for bass. These include a handy “Octave Up” effect, which adds a note one octave above the original while retaining your natural bass sound—complete with adjustable drive on the octave-shifted note—plus favorites like Slow Gear, T-Wah and a Defretter effect for instant fretless sounds. Using the Tone effect preset, you can get quick tonal variations with preset EQs like “Bottom Boost” and “Mid Shape.”

Incredibly Warm Overdriven Sounds and More

Want some extra bite? Switch on the ME-50B’s Drive effects, which include settings like “Muff Fuzz,” “Bass Driver,” “Natural” and “Metal” to give you a range of overdriven/distorted sounds. A new “Hi Band” effect creates a distorted sound on the high frequencies while keeping the lower frequencies intact—perfect for creating complex tones while keeping your original playing dynamics. There are also four synth bass sounds with superb tracking and natural feel.
