Bought new, it didn't work straight out of the box, Roland Australia were not helpful.
I live in Australia, and didn't want to pay the crazy prices for pedals in retail stores here, so I purchased a new one from eBay overseas. It is a flimsy looking pedal, light weight plastic and low grade built-in cable, made in China, and seemingly with a lack of quality control or testing. It didn't do anything when plugged in to my Roland VR730.
I spoke to Zach and Andrew at Roland Australia. Initially I was told to just buy another one! I was later told I can return it and only if he eBay seller was an authorised Roland distributor they could help me. There is no way for me to know that, and they refused to help find out. After 45 emails, I just gave up and bought a better quality pedal. Quite simply... I bought a brand new pedal. It doesn't work. I just wanted a pedal that worked. I would look at other expression pedals, given mine didn't work new, I imagine the durability of these is questionable. You may have to replace your EV-5 every 6-12 months.
It was not a pleasant experience, and I have heard similar stories of a complete lack of care and support by Roland Australia from other musicians.
