my small clone analog chorus pedal isn’t working. the status light goes on, but the sound isn’t effected at all by the pedal. i already tried changing the knobs and depth settings, and tried changing the battery and using a power supply. i bought the pedal off of sweetwater a few weeks ago, but it didn’t work, so i got it replaced with another small clone, but to the same answers. i don’t know what to do anymore. does anyone have any advice?
