Accu-just hitch pins and tuning stability

[Andrew and Rebeca Anderson]

Te, hee-hee,:-D Terry, you take the pie.

I have two customers with baldwins that have accu-just hitch 
pins.  The shared strings apparently do slip around those a lot 
easier than I'd prefer.  I just got called back to one I did a large 
pitch-raise ( 60+ ) to about a year ago.  I had called for a 
follow-up in 2-3 months.  The unisons weren't rock solid, it was 
about 5 cents flat.  I'm used to coming back to better unisons but 
this and the other baldwin with those derned hitch pins defy 
me.  Perhaps the third tuning after a large pitch correction will be 
the charmed one on these.  I was just wondering if I was missing anything.
