Just got this for Christmas (2015) and can't stop using it...don't know why I never checked this pedal out before...it's hands down the easiest chorus stomp box ever made...one knob and one switch...dial it in and off you go...it's true that the power supply is a strange mini plug that you have to buy (if you're like me and hate batteries) but (and I don't say this often...if ever) I like this pedal so much that I'm willing to run the Small Clone power adapter (9DC-100) as a stand alone even though all my other pedals plug into my 9v power block...it's a fairly large footprint so some of you may need to make room on smaller boards...overall this chorus pedal is well made (although opening the battery lid took some effort) and sounds amazing...AND IT'S SO EASY TO USE!!!
