Question UV7BK setup

Hi there!

OK, I've got this '97 UV7BK now for some time, and the guitar just isn't right.

I've been tuning and customizing guitars since '86 so I like to think of myself as a little knowledgeable on guitars and their setup. These are my findings:

The bridge is in it's lowest position, screw-wise that is, and the action is still almost 3mm at 12th and 4.5mm at 24th fret. The neck's curbature is OK though, and it doesn't seem to be ****ed up. I need to lower the action, and make it a less forceful guitar to use for arpeggio's and such. I cannot lower the bridge, since it is already at its' lowest position. Normally at this low level the strings should be hitting the frets. This can only have two reasons :

The bridge has always been setup like this and neck has gone "positive" (if seen from the upside while holding it then a forward movement from the neck along time under the tension of the strings. The option here would be to tension the neck negatively at the rod, and compensate the action in this way.

The guitar was badly assembled from start, and this setup is how it came from factory and has been used always. The remedy would be disassembling the neck and put some sheets of paper between the joint and the neck to compensate for the current positive angle of the neck/body joint allong with possibly some additional rod-setting alterations and trem fine-tuning to get it perfect.

Now, I need some input to determine how to proceed. What so you think? Don't you find the action too high? This baby should be setup as a JEM, but it seems to have been setup and/or maintained badly. It can be fixed though, but knowing what's wrong with it.

Please let me know your thoughts,

Best regards and thank you in advance,

D.

Re: UV7BK setup

Is the bridge sitting level or is it pulled way forward?

If the bridge is fine, it's probably the neck angle. Check if the neck is angled forward. Have you had the neck off yet? Maybe somebody put a shim at the headstock end of the neck pocket ... or altered the pocket itself. Sight down the guitar or use a straightedge to check the neck angle. It shouldn't be too hard to find the problem.
