Just wondering if anybody has had a similar issue and can advise of cause. (I won't mention the specific pedal out of respect for the manufacturer - no need to generate any negative press for something isolated to my unit / situation.) I have a rotary speaker pedal on my board, and when the pedal is in bypass mode I feel like I can still hear a hint of the rotary effect. Just a hint. What could be the cause? I didn't think the bypass switch could fail in a way that it would only partially bypass...but who knows. Now, the pedal does have LEDs that are a visual indicator of the rotary speed, and (without being a master of electronics) I wonder if the mechanism in the pedal that is triggering those 2 lights on and off is causing interference in neighboring pedals in the chain? Any thoughts?
