I'm pretty certain I'm going to go with #2, the 2019 non 10 top new 594. I like how it's not too charcoal/grey/silverish like the others and has some brown in it. I have a feeling it may not actually be a "charcoal burst", but a "charcoal smokeburst." Would anyone know? I also prefer the burst on it to the others along with its tigerstriping horizontal lines. It being a new guitar appealed to me as well, even though I normally buy used.
I really liked #3 (2019 new 10 top), but the price is a little much for a 10 top and I think I prefer the more subtle brownish charcoal of #2. #1 (used 2018 non 10 top) was probably a close second to #3.
Even though it got the most votes, I think I liked #4 (2018 used 10 top) the least. It was a bit too light for me, almost like a silverburst.
