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!

Everyone knows that the fundamentals of good bass tone are compression and EQ. That’s why the ME-50B features two dedicated sections for these essential effects. The Compressor/Limiter uses advanced COSM modeling—including a “Natural” compression setting that retains the nuances of your playing—to give you tight, punchy tone. Simply select the compressor “Type” and adjust the Sustain/Threshold knob to get the tone you want. The Master section includes a 3-band EQ with a sweepable mid for precise tonal shaping.

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.”

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.

Sound On Sound recording is very popular with guitarists, and now bass players can build their own loops, too. But the ME-50B can do even more. Using the new Kick Drum function, players can tap in their own kick drum and create loops over the beat. If that’s not enough, check out the new Sound Hold function, which lets you endlessly sustain a low note while playing over it. With the ME-50B, bassists can take their playing to a whole new level.
