Used with DC supply, not battery (horrible battery access). Only
unprocessed sound on pushing pedal , but the LED comes on, usual brightness.
I've not had any failure with it, normal function.
Somewhere between 400R and 1K in series with the supply, simulating
dirty contact, processing fails and LED on but only feint.
So not power connector diverter switch or input Ring/Sleeve contact
problem presumably. PbF problem, but where is most likely?
Incidently is the casing really ABS? says so on the mold mark inside but
it has the look and feel of nasty breakable polystyrene
