The strings on my A9 are already dead sounding but I've been afraid to change them. Last night I took the strings and tailpiece cover off my cheapie Johnson mandolin to see if I could figure out what to do, but it's a little confusing. I found one illustrated "how to" deal on the web but it didn't help me much. Any advice? I'm scared to take the strings off my Gibson because I know nothing about bridge placement, etc. Thanks. Sucks being a newbie.
