    picked up one of these used as part of a trade. No sound. I can play my clean signal but as soon as I activate the effect all sound is gone. Blue led lights up but no sound. Quick google search shows a few people with the same issue. Took it apart. Nothing appears to be burnt or melted. Any ideas? Thanks guys!
  2. Change the battery?

    Just as a test, try running the El Grande with an AC adapter and NO battery. I had another MXR pedal that acted the same way. Worked only with an AC Adapter BUT would not work with a battery. Probably had a simple problem that I eventually had repaired.
