Received a bone saddle from Bob Colosi today. It took about an hour to prep it and install. Directions from Bob were easy and I kept the Elixir Nanoweb strings so I could do a good comparison. I have read a lot of opinions on the sound change using bone both positive and negative. So decided to try it myself and form my own opinion. Sound and tone are very subjective, so I wanted to discover the differences for myself. I have to say, after the install, I will keep the bone saddle on my 414ce. Acoustically, it has more mid range and a crisper sound. Aplified through a Fishman mini, smoother sound and accented bass. The difference is not overwhelming to the point that I needed to make the change, however, the changes were positive.
