@Chris: I had never seen those acoustic models before, what a nice looking wood cabinet around the amps! And all early 90's as it looks.
So there wasn't only the Guild G-500 (was there also a tree name for it?) but also an early 90's Guild G-300 Tamarack, G-600 Aspen, Guild Sequoia (G-700?), the stool amp G1000,...
Here's a nice G-300 Tamarack, similar to what Grot has.
