Should I adjust the truss rod on my new Corvette 6?

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?

 

Well, I had to go yesterday and while away I was thinking and decided to flatten it - it was a hard decision... and a bit hard-going at first. I spent three hours setting it up: I did three 1/8th turns, then loosened the strings and, after not seeing much change, I put it back into the bag to stabilize. today, as I took it out, it was much better - but it is still not perfect... well anyway, thats better than was...

Oh, and thanks, nojazzloco! yes, mine has a bit of a neck-dive, too, but not too much: it doesnt like being angled upwards, it usually stabilizes at horizontal. The problem now is that I cant find a short (for slap) and comfortable strap anywhere... oh well
