I've seen many questions and comments about getting strings to sound older for a vintage sound.I lay my bass on a towel with strings up. Slip plastic wrap under the strings and tape it in place to protect the body. Use a tape that is easy to remove. Using shellac,dab a little on one string at a time and run up and down the string quickly to cover the string using your finger covered with a rubber glove.use just enough to wet each string. It will dry within minutes Have some denatured alcohol on a lint free cloth and wipe all the strings till you can't see or feel any shellac at all. This will all dry within minutes also. There you have it. No oil and remember ... nothing containing salt like chicken grease or potato chip oils.Salt will eat away at the metals over time whereas the shellac protects from dirt and salts from getting to the core of the strings.Don't have shellac? try a floor wax... acrilic is best.
