Lately, I have been playing bass at church. I use an Agile jazz clone. It's been an OK bass for about 5 years, but recently, it has started a buzz that goes away when I put my hand or fingers over the strings. My worship leader said that he would pay to get it looked at, but most repairs start at about $60, and that's probably about half what the bass is worth. So, what's up. Should I have it looked at or just buy another bass? Is there some easy fix that I could do? I am not Mr. fixit, but I can use a soldering gun. Thanks for any help.
