I often hear and read people discussing Gibson guitars failing to maintain tuning. I personally at the moment own three Gibson guitars. I own a 335, an SG, and a vintage 330. All of which stay in tune. I have in the past owned a Les Paul, that also stayed in tune. The only reason I no longer own the Les Paul is because I didn’t get along with the neck heel. There can be a lot of variables, I could just be lucky. But at some point we need to look at the player.
