For hollow-body Guild 6 string acoustics, I've had a Tacoma D55, an '80s F50 blonde, an F30 with an arched back and a '69 D35.
For acoustic-electrics, I've had a mini-bucker CE100 single, a Guild Geo. Barnes, a mini bucker DE500, an M65 and a mini bucker DE400.
For classicals, I've had an '85 Mark 5 and a '72 Mark II. Nice guitars, but the action was too high on both of them for my old guy hands.
For 12s, I've had a G312 (like GuildMark) and then, all at the same time, an F212 cutaway, an F212xl, and an F112. I liked the 212xl, but it was a bit slow coming out of the box. Sounded like a baritone voice. The 212 cutaway was okay but not great. Never cottoned to the G312. The F112 was a dandy, with a quick-spirited tenor voice.
For solid body electrics, I've had a Nature Boy finish S100 with the big buckers, 2 circa 2000-2002 Bluesbirds.
For basses, I've had 2 JS II fretless basses, a '66 SF I bass with the pickup near the bridge and a later in the '60s SF II bass with Bisonics and the master volume/suck switch harness (hated it). I had a '70's M85 II solid body, too. Heavy.
Instruments that I've not owned but have played enough to have an opinion about are: X500s, an X700, X175s, an A350 with a DeArmond 1100, a 60s Braz D50 and a few F20 and M20s.
Sorry for the long list, it just came out. I originally was just gonna list the 12s. Sheesh!
