I went ahead and opened up the unit- nothing to lose. The 1/4" female
jack was detached from the PCB at the insertion side (which I assume
is a ground)Intermittent contact of course. Fixed this with my trusty
soldering iron and as I was re-assembling everything- the leads from
the piezzo came off in my hand. !@&%##
So I'm off to my friendly drumshop this weekend. I am soliciting
excuses (explanations, lies) from members who have unsympathetic
spouses.
