I bought a Warwick Corvette off of E-bay. I put some new strings on it when it arrived and did a minor setup on it. I got the action the way I liked it, but there was buzzing on the G string when it was fretted. It is most noticable on between frets 2-7, but it buzzes all along the fretboard. I then raised the nut height, and the string height at the bridge, but the buzzing is still there. And it is only on the G string. I like my action on the low side, and I have a medium attack. The other strings buzz when I dig in real hard, but not when I pick normally. The neck looks to have adequate relief, after I loosened it a quarter turn. Does anyone have any ideas?
