I've sold off a Lakewood M-32, a Huss & Dalton CM, a nice J-45, a sublime (but beat up) AJ, and a handful of others I can't recall at the moment. I'm generally okay with having moved on from the ones I did, as I had my reason for each at the time. The one and only that I wish I hadn't of let go was a '97 Gibson Chet Atkins SST.
I bought it shortly after my father passed and it got me through some tough spots, though I never really used it to it's full potential (e.g., rarely plugged in). And honestly, it was quacky plugged in and didn't sound all that great, tone wise. But I loved that guitar. Sold it when money was a bit tight to a nice fellow on the forum, but wish I had it back.
