I sold this pedal, but it was returned with the reason "the flanger sound doesn't work." I tested it and it worked normally. However, as the presence of a problem is unknown, I will sell it as is. Returns are not accepted. Shipping Free shipping Please note that I will not offer discounts as shipping is included. I usually ship within 24 hours. As I am also selling on other sites, if purchases overlap, I will prioritize the buyer who purchased first. Used in a smoke-free environment. I would like to sell to those who can complete the evaluation smoothly. Please understand that returns are not accepted for used items, so please only purchase if you agree. Thank you.
