So, another update....
I got my guitar back last night, and looked it over pretty good. The first thing I noticed was a broken off nut in the guitar case, so I am assuming they changed the nut. I checked the tone pot, it was exactly the same as before. I played the guitar, and although the intonation problem seems to be gone, the fret buzz is as bad or worse than it was before. So basically, the two things that were important to me (fret buzz and bad tone pot), either got worse or weren't touched. I would say that I am pretty pissed off at the moment. I know this isn't the most expensive guitar out there, but IMO, this thing is unplayable in its present condition. Not knowing where to turn, I called the GM of the store where I bought it. He has played the guitar before and is aware of the problems, and even agreed with me that the tone pot is no good. He also agreed with me that when he played the guitar, he was getting a lot of fret buzz too, but tried to convince me that this was "normal". Talking with him last night, he was, again, trying to convince me that I was being too picky on the fret buzz and that the fret buzz I get from my guitar is normal. I told him that I have two other guitars, one of which I bought from his store, and neither of them buzz AT ALL when I am fretting the string properly. The only time I get ANY fret buzz is when my technique is poor. He seemed to want to press the issue, and I was getting annoyed, so I said "OK, I'll come down to the store right now and you can start taking guitars off the wall and if I play them and they all have fret buzz when fretted and picked properly, I'll agree that fret buzz is normal for guitars bought from your store." I think he got the point.
So, I don't really know where this leaves me. IMO, this guitar is a cheap low-quality piece of crap that is essentially unplayable in its present condition, and the techs at Schecter lack either the interest, the ability, or both to fix the guitar to play properly, and Schecter in particular doesn't seem to give a rat's ass that this is the kind of product they are putting out in the market, nor that this owner is pretty ticked off about it.
So, to make a long story short, I think I am in the market for a new axe.
Mama Mama many worlds I've come since I first left home.
