Having dusted off my Bass PODxt, have found that it is receiving a signal as the tuner is working,but nothing coming out of the Moder/DI output or Headphones output; will hook up through USB and I've updated all drivers and firmware, but nothing at all. No connection crackle or hum, just seems dead. Is there anything straightforward this might be before I send this off to someone to repair? Thanks for any advice
