I own a Yamaha Eterna, bought it in 1986. It’s very durable, as Yamaha guitars usually are. Did a lot of traveling, for a few years, after I bought it, and it handled it well.
It has a more rocking, or folk rock, sound, as it’s more jangly, and bright, in tone, which is why the folk purists don’t like it. I love that sound, which is why I bought it. It was an excellent purchase, for $180 (with a soft case), at a local guitar store, back then, in 1986.
It is as good, as any mid-low end Yamaha, and has served me well. It is laughable what some say, who know nothing, & sneer, & pretend to know it all. Yamaha started Eterna, in the mid ‘80’s, then discontinued it, in the 90’s. They revived it, just recently, a couple years ago. You can buy a new one now, if you want a durable, acoustic, with a bright, fluid tone.
