I am an experienced guitarist and own several US made solid wood guitars. I need good advice about my Taylor 414ce, which is my preferred acoustic for its wonderful sound, comfortable shape and sweet neck feel. I had it set up with low action when it was new in March 2013. It is so low that it sounds great and plays wonderfully, except that there is an obvious fret buzz in the first position on the high "e" string. I don't want to change the neck adjustment if I can help it, and it seems that just a slight increase in string gauge would do the trick. I thought a good choice would be a light-medium. Presently it has D'Addario EXP light gauge with 12-16-24-32-42-53 sizes. The Martin M545 Light-Medium set is .0125 .0165 .0255 .0335 .0435 .0550, which should increase the relief just enough to remove that buzz. It seems that given the set up is low and the neck presently has no relief, that this should work well as long as the guitar can structurally withstand the slight increase in pull. Any thoughts? Your input is greatly appreciated. I wouldn't mind a bit of increase in volume, either. I play in nursing homes unplugged, so I could use a little more support for my voice. Thanks for your help!
