My Corvette Standard 6 LH arrived at last a week ago - and im very happy about it, except for two things: weight and setup. It was already set up at the factory, but the dealer altered it, so when i got my hands on it the strings were quite high - and I like low action. So, naturally, i started adjusting the bridge (why do they have to make it this complicated?) and the Just-A-Nut 2 to get lower action. And then it started buzzing - not just at the frets closer to the head, but even more beyond the 12th fret, on all strings! so i had to put the string action higher, but there is still one thing: with tapping I get a naughty dissonant sound - that means the fret-to-nut part of string is so high that it too begins resonating... I compared the neck to my other bass' neck and that was flatter - so i think I will have to adjust the truss rod... but you know that that can ruin a neck... so what should i do now?
