do guitar shims impact tone
To minimize the sound quality loss, you can use shim with the same material as your bridge if you think you must use shim to adjust the action. Personally I donât suggest using shim to raise action. Simple and best way is buying a new tusq or bone saddle and replacing the old one.f it is too low (less than 1/16ââ), the next thing you can do is modifying the height of saddle. There are several ways you can modify the saddle height. One is replacing the old saddle with a new one. You can buy a new saddle and modify it to the height you want. This is the most direct way.
