The lightweight could mean that it’s semi hollow. Maybe, maybe not. Take out the pickups and see what you see.
all four pots are coded 38 K and 504042
It is really nice to see an example such as this one at 39 years of age with the original wiring harness, pots, everything, etc. fully intact and no broken solder. The pots work just fine with no issues. Not a huge fan of the Screamin 1982 pups but working the volume and tone pots can make these things sound pretty decent. No real reason to change a thing on this one, yet. LOL
As far as hollowed out EGs: I recall one particular 1980 example i had many years ago with a pretty nice laminated flame top and a dark burst finish color. I believe the guitar had UD pickups and the guitar weighed about 7.5 lb.
It sounded a bit like between a Les Paul and an ES type guitar; very interesting guitar.
I prolly should have kept that one. Oops ......
