Just picked this up yesterday from the good folks at Blues Angel Music in Pensacola. It is my first Koa guitar and I am really enjoying the tone. I wonder if using medium stings would be recommended on this model?
What model is that? I would only try medium gauge if it's recommended. Also, play that guitar a lot and you will be surprised at how much the Koa opens up. Koa takes time to break in but once it does then you will have an exceptional sounding guitar.
