I hadn't played it for a few months and decided to hook it back up to my rig. To my surprise it no longer 'wahs' at all. When I move the pedal up and down the signal goes from low to high volume just like a volume pedal but there is no wah sound at all. It's really weird. I did just remove the base plate to install velcro so I'm concerned I might have disconnected something but I don't see anything noticeable.

Has anyone ever experienced anything like this or have any idea of what might be causing this? The pedal was Fasel/volume boost Modded if that makes any difference.

Thanks in advance
