I just bought a new danelectric chorus pedal.I liked the sound. So the guy at the store gave me a new one in the box not the one i just played of course because it was display. I got home and it dosent work. The light is on but makes no different sound. Played with all settings exactly the same clean sound. Is it my pedal or is it that my amp can handle it or something. I have a fender Frontman 15g(ik im working on getting a new one). Thanks.
