I wish I had never sold my ME 80B... ### ⭐⭐⭐ Great product, Great sound, not so great manual. *by A***I on October 6, 2014* I had a mini-tour in a different country and I wanted to travel light. I left my pedal board at home and bought the ME-20B because of its size. As for the sonic quality it is excellent and I expect nothing less from Roland. I was able to program 10 different settings, that were wildly different, and made it sound like I brought 4 different basses with me, it was that dramatic. Getting there was another story. In manual mode it wasn't difficult to discover the various potentials of the effects in combination. Writing and saving patches was another story. The manual is poorly written, it lets this fine product down. After a few baffling weeks I developed my own understanding and I was confident I could change patches on the fly in program mode. I'm glad I started early learning the ins and outs otherwise there would have been dramas once I got on the road. In performance my fellow musicians and sound people were loving the sounds, so it was very worthwhile to go through the trouble it took to tame the beast. ## Frequently Bought Together - Boss ME-20B Bass Multiple Effects Pedal Board - SONICAKE 6 Inch Guitar Patch Cable Guitar Effect Pedal Cables Noiseless 1/4" Right Angle TS Mono Cords for Effect Pedals Black 6 Pack - BOSS SD-1 SUPER OverDrive Effects Pedal for Guitar and Bass - Mild to Moderate Tube - like Overdrive Characteristics Ideal for Clean and Driven amps.
