Well, G&L repairs got back to me. About all they had to say was "alder":
You are correct the body wood is alder, production date of your Climax is March 23, 1993.
Although I take the descriptions of tone woods for electric guitar with a large grain of salt, Fender have this to say about Alder:
Red alder boasts many sonic advantages. Not especially dense, it’s a lightweight, closed-pore wood that has a resonant, balanced tone brighter than other hardwoods, with a little more emphasis in the upper midrange. It imparts excellent sustain and sharp attack. It’s very easy to work with and it glues well. Notably, alder also takes finishes well — with a light brown color and a tight grain that’s only slightly visible, it’s ideal for solid colors rather than the transparent finishes that look so good on ash.
I think I just got an alder body at the upper end of the density range.
Case closed.
