Yes I was very happy to get this working - of course, in my haste, the neck is on crooked (it's about 1 mm off!) the screws must have "gone in " on bad angles (just plain atrocious workmanship!)
I'll have to take it off, put dowels in and then try again.
But at least I know that kind of fret levelling will solve the problem.
the shieding tape wrapped around the tuners did help too.
