Boss ME-30 Multi-effects pedal with 28 built-in effects. The ME-30 offers everything from distortion, overdrive, chorus, delay, reverb, and modulation, giving you the tools you need to really shape your sound. Along with the precision of Boss's COSM technology, the ME-30 also includes analog drives and distortion, a notable feature for a multi-effects pedal from the 90s. The built in foot pedal also means you get wah, volume, and other expression options. This unit also includes a phrase trainer function allowing you to loop up to 12 seconds of audio from the AUX input to help you learn the tricky stuff. I wish this pedal had a little more volume in the headphones, but other than that all works as it should. For Studio, running through an Amp, or just practicing this pedal has it all. Included is a 9V adaptor along with a copy of the users manual to get you up and running right out of the box. Pedal sold as shown, original box not included
