I played a gs mini koa and a new gs mini spruce/layered walnut yesterday.
The Koa had the 3 normal Taylor knobs but the specs said it was the ES-T system.
The Walnut had the ES-B.
Plugged in an acoustic the Koa won. Now the Koa did have the three screw in the bridge. Does this mean their specs were wrong and it is in fact the ES-2?
Who knows. I liked the Hog the best but it was only acoustic. ¯\_(ツ)_/¯
***althoguh the new walnut didn't sound as "good" to my ear plugged in, the ES-B system was louder
