Thanks, Dave. Yes, my battery was charged and my 1/4" plugged into an amp. The electronics were on and working.
There seems to be a new wrinkle. After my failed attempts at upgrading, I took it to a gig tonight and there was some weirdness with the volume control. When I turned it all the way up, it wasn't at maximum volume. Then, as I backed it down, it actually got louder before it got lower. I wound up using the magnetics for most of the night.
