this is such a wonderful saddle to put into a 000 martin, it has made a world of difference in my tone. the piece is also very beautiful, perfectly polished and my piece has a slight pink color to it which looks amazing! minor sanding is all that is needed to make the action the way you like it. The increase in tone is amazing, the fwi saddle adds great overtones and strengthens low end and highs perfectly. it really just makes the sound so much more punchy and mellow at the same time its really great! i replaced a factory tusq bridge and wont be going back! This is a practical worth while investment in tone, highly recommended
