Re: So I just have bad luck with Jems/Pia?
with 1 exception; My 10th Anniversary. The frets were all over and it drove me crazy until I brought it to a good luthier. He diagnosed it as the unfinished(barely finished) neck had enough expansion and contraction through seasonal changes(in New England) was causing the frets to come loose. He went thru and glued them all down, and from then on, it was perfect(sure wish I still had it......)
Correct problem, wrong diagnoses. It was well known at the time there were alot of 10ths with unseated frets. I had a few myself.
