Yes. I have a Yammerhammer fg200. I bought it in 1974 or so. I never liked it because of the "narrowness" of the finger board. I had learned on an old Gibson SJ. But the fg200 sounded good. balanced and even toned if not loud at least it has enough volume. I recently bought a Gibson Songbird. I was so happy to have a wide finger board again. I was curious as to how much wider the Gibson was. I compared. YIKES! the fingerboards were EXACTLY the same width! I was stunned! For almost thirty years I had been convinced that the Yamaha was narrow. I then looked closely at the SPACES between the strings. The Gibson had "ample" spaces and the Yamaha's spacing was not only narrower in some but was inconsistant! I couldn't believe that for all that time I hadn't noticed the spacing was off. I am going to replace the nut with one that has "Gibson-like" spacing.
