Picked up a Catalinbread Dirty Little Secret III the other day used on reverb.com. Went to try it this afternoon for the first time and I'm having trouble with it. I get pass through sound with it off but when I turn it on I get nothing. The red light comes on but no sounds. Anyways, it is as simple as that. Not sure what the issue would be as this is a pretty simple pedal. I'm sure it's going to be something simple that I am just over looking. As always, thank you in advance for any or all help!
