Bob Colosi says on his website www.guitarsaddles.com
" Often overlooked in terms of the sound your acoustic guitar produces,
the saddle plays a vital role in this regard.
The material and construction of the saddle, as well as the bridge pins have a significant effect
on how the vibration of the string is transmitted to the top of the guitar, and if used, how an undersaddle transducer (UST) receives a signal from the saddle for amplified playing ".
I always pose one very simple question in response to the plastic material versus natural material quandary:
How many plastic saddles, nuts and pins do you see on guitars made by the elite manufacturers..... where only the very best components will do?
