My effect pedal is not as loud as it was just 2 days ago. I have to turn my amp all the way up to have an almost normal volume just for practicing alone. My amps are fine and my cables are fine. It just happens when I plug my pedal in. What's wrong?
google Zoom pedal issues and try a firmware upgrade/reboot
This is the model. There is no firmware you can update. You plug it in, and play it.
