Tinker, don't listen to them! I wouldn't play anything but my three Martins!However, a dear friend and super songwriter (who plays a ugh! Yamaha!) likes to tease me that the reason I have three is one is always at Nazareth (which is only about 45 minutes from me in PA).
Sure, there are other guitars out there -- but I want my estate to read "MARTIN guitar" not just "guitar". Seems to me the anti-Martin group are just expressing well earned sour grapes.
