You're looking at a Boss PS-5 Super Shifter in like-new condition. It was bought a few months ago brand new from Guitar Center and used only twice. No noticable cosmetic imperfections, and needless to say it performs flawlessly. This is probably the most highly regarded pitch-shifter out there, it can do virtually anything you think of: check out some clips and reviews
HERE. The pedal comes in the original boss box with all the paperwork.
Shipping will be a flat rate of $10 or if you happen to live in the MD/DC/VA area I'll be happy to arrange for pickup. Feel free to contact me here on eBay with any questions.
Thanks for looking!
