Simply one of the best chorus pedals on the market. Kind of a better sounding take on the EXH Small Clone - this one has all the bells and whistles: mix knob, depth toggle, stereo outs. Sounds amazing on guitar and bass. Only moving this because I was able to get a vintage polychorus and am using that these days. Runs 9-18v, has small velcro tabs on the back that can be easily removed if desired. No box. happy to answer any questions or provide additional photos upon request. Thanks for looking!
