Jim Mouradian has been "the Man" in the Boston area for years.
For years I never let anyone but Jim touch any of my guitars.
He's a good guy but you need to call him and book the work usually a month in advance.
If that's not problem then he is your man. He does really really good work.
About a year ago I discovered (thru a friend)
Steve Morrill "Morrill Guitar Repair"
I have to say he is probably as good as Mouradian and the wait time is waaay shorter
because he is not as well known.

he did a refret on my Carvin DC727 and saved it from going on Ebay.
he does great set ups and is very reasonably priced and a good guy to boot!
Now he basically does all of my setups and mods.

They were friendly and up front. Never had anything fancy done but they are well known in this area. Search on the name if you like.
Good luck and let us know what you find.
