When I was a kid it seemed like all the little cheap guitars my family bought for me to drag around had open gear tuners. When I did finally buy my first decent guitar, I was well satisfied knowing that the closed gear tuners were a mark of better equipment. Now I see Martin and Larivee and probably other acoustic guitar makers going to open gear tuners on some very expensive guitars. Why? Is this just a fad? Are there advantages I don’t know about? Should we expect the electric guitar industry to follow suit?
