Hi Alan, As stated by drivewithken the problem will be the suppressor having gone short circuit inside the foot control. I would replace the item rather than throw it away because it is there for a purpose to stop rf interference. I obtained a replacement from Radio Spares but i had to buy a minimum of 5 which cost £14.11p inc P&P. The replacement is slightly larger than the original but it still fits inside the pedal. The RS website is rswww.com
