Hey guys! I just bought at Warwick RockBass Corvette 5, but am having a small issue. On the B string, the 3rd and 5th frets buzz, and on the E string, just the 3rd fret buzzes. I tried playing with the action on those strings, but nothing. I must add that I can work with my hands, but have almost no idea how to fix a bass. So, does anyone have an idea as to what I might be able to do to fix the issue, or will someone like me have to just bring it in and let the pro's do their work? Thanks guys!
