Sorry, still having the same problem with them5 going out raNDOMLY AND UNPREDICTABLY. WITH THE ORIGINAL POWER SUPPLY. Ways to replicate the problem include:
1) repeatedly stomping the on/off footswitch (this is intermittent, and not at all predictable, but it does happen)
2) hitting the tap tempo switch (again, intermittent, but it *will* replicate the problem eventually)
3) turning on / off another pedal in the chain
Changing presets and then returning to the one I was using resets it and the sound returns, but this is a serious problem.
SWITCH OFF /ON IS THE SOLUTION BUT NOT AN OPTION IN LIVE AT ALL PLEASE HELP
ISSUE IS BEING FILED SINCE 2012. NO SOLUTION GIVEN. OR I MA AWARE
