Ridges forming in the finish of my 2017 J45...and I love it! in Gibson Acoustic Posted June 14, 2018 · Edited June 14, 2018 by jjrpilot · Report reply When it first arrived it was glassy smooth but now, as you can see, the varnish is slowly settling into the grain of the wood. I LOVE this look! This J45 Standard has really started to open up and has gotten richer as I'm able to play it almost everyday. I'm doing my best to avoid dings, and won't be abusing/relic-ing this guitar at all. I want it to show its age honestly. I'm just keeping it clean and humidified. I'd love to pass this guitar down to my daughter some day.
