Bizzare Truss Rod Situation, Need Help!

I have a Jem 7VWH that I bought new about three years ago. When it arrived, the action was high and the trem was tilted forward. After I adjusted it, it played fine so I didn't need a truss adjustment.

I reject alot of VWH's for the same reason, neck too straight and won't come into enough relief.

I actually bought it from you Rich. Is this something that a qualified tech could fix?

So long as you're not in a backbow, there's nothing really to "fix" other than you'd like to know if you needed to, you could get a little more bow out of it. To fix it you need to get some bow into the neck. I use heat and pressure. You're not just trying to make the wood shift as much as you're loosening the glue joint between the neck and fretboard, so when it hardens again it's hardening in a bowed position. But you never really know what you're going to get when you do that. It can be a temporary or permanent solution. A totally permanent solution is to wait until you need a refret, and then either open the slots a little or use smaller tanged frets. Then the neck would be "weakened" enough to pull into a slight bow under string tension. Some guys would just plane the bow into the board, either with a neck jig that simulates tension, or by levelling the board with the truss rod torqued. That's alright, but not my choice. If you wanted to do a fret level with tension or a tightened rod, I'd say that could be your best intermediate and least destructive fix. If it still plays like you want it to, but with too much low E noise, that's the best fix.

Then it should have plenty of relief. Surprising you say the trem angle was off and action was high. Who is this?

OH, 3 YEARS ago, here I'm looking through records 3 weeks ago!
3 years ago I almost never personally setup new guitars, only used. That changed when I got a return on a guitar that had been drop shipped and discovered the "perfect setup" that was supposed to be done on it was crap. Everything passed through my hands from that point on.

After reading my options, it looks like a fret level is my only realistic option. Probably followed by an E-Bay auction.

Well it had enough relief [I guess] that you never even tried adjusting the truss rod for 3 years

It's always been in full relief. VWH's what whatever reason have very strong necks!

The guitar isn't a lemon or anything, it's perfectly normal for ebony to expand more or shrink less than the maple. Its very strong. In my opinion, I'd rather have a neck that didn't need any truss rod pressure than one you had to crank. Over the life of the guitar, it should pull into more relief, not less. After a good level it sounds to me like it would be a perfect guitar, certainly not one you'd "dump"

For the nut to be loose(ish) could also be a slight shrinking of the maple over time. That's how tuner nuts get loose, too. It doesn't mean there was that little pressure on the nut when you bought it. On a new guitar the maple only has to shrink by a few thousandths or so across the entire length of the rod to make a loose nut. If the ebony isn't shrinking at the same rate (or at all) it would keep the neck straight over that time.

If you are only after 0.1mm extra relief my advice would be to go for 10s or at least a hybrid set for a while - just try a few weeks.
I'm pretty sure the hybrid 9s will do it (if you play 9s - otherwise go for hybrid whtever you play) and you'll be happy.
Also the extra tension that .48 will have over .42 will reduce the buzz anyway so you are killing 2 birds with........wel you know how that goes.
