When I travel, I am in the habit of scoping out local high-end guitar shops for any interesting used acoustic guitars. Staff at these places work there because they love guitars too, so it's easy to just walk in and ask if anything interesting has come in recently. They will be happy to tell you which guitars they are excited about.
Wade's Guitar Shop. They pulled down for me a 1990 Gibson J-30 with Vintage Sunburst finish that had just come in two days prior from the original owner.
The Gibson J-30 was made from 1985-1998. It is a dreadnought model with a Spruce top and Mahogany back and sides. It was/is popular as a poor-man's Hummingbird as it shares the same specifications without the higher end appointments and pricier tag.
The guitar was in surprisingly excellent condition and, having benefitted from an in-shop set-up, it was a pleasure to play. I appreciated the slenderer neck profile than on other Gibson acoustics I've come across. The kicker was when the staff pulled out its beautiful original deluxe Gibson case in excellent condition as well. After Wade was willing to work with me on the asking price to include shipping it back home, I pulled the trigger on my very first Gibson guitar. This is going to be a lot of fun to play, and such a pleasing guitar should be easy to pass along to another happy owner eventually.
