Up for sale is a lightly used EXCELLENT CONDITION Boss ME-50B. This has only been used in a smoke free studio and only a few hair line scratches on the side of the chassis that cant even be seen unless looking under a close light. All the pots move freely and Expression pedal still has the grease in the crank. This is a great pedal with all analog effects except for the compressor that uses the COSM technology. This was purchased less than a month ago from a fellow talkbasser. It is still in the same condition purchased because it was barely used. I just wanted to tweak with the effects and have a multi-effect pedal around. Why selling so soon? Well, it's gear and I got GAS for another bass and need all the funding I can get. From the website: The BOSS ME-50B Bass Multiple Effects with COSM puts world-class bass effects in a rugged floor unit with easy pedal-style control. Effects are divided into 6 sections (Compressor/Limiter, Master EQ, Filter/Tone, Drive/Synth, Delay/Modulation, and Expression Pedal), giving bassists a range of unique and powerful tones including new effects like Sound Hold, Octave Up, and Kick Drum—all with easy knob-based control. Boss ME-50B Bass Multiple Effects with COSM Features: - Floor bass multi-effects processor with super easy, knob-based controls - Killer COSM Compressor/Limiter and Drive effects, plus T-Wah, Slow Gear, Defretter, and much more - Innovative Sound Hold function sustains a low note while playing over it - Sound-on-sound recording with new Kick Drum effect for keeping time - Dedicated knobs for each effect section—no menu-surfing! - Easy Tone effects with preset EQ templates for quick tone editing - 3 footswitches and onboard expression pedal for easy realtime control Included is the Pedalboard, Original Box with all packing materials, User Manual with all paperwork/warranty card and I will include a new set of AA Batteries (x6) in the deal. This unit runs off batteries and optional Boss power adapter. $185 SHIPPED anywhere in the LOWER 48 USA.
