I recently saw Fretboard Journal's video on John Reischman and his Loar-signed '24 Gibson F-5, and it came up in a subsequent discussion that Reischman's Loar is perfectly matched to his playing style. From listening to John's tasteful picking with the Tony Rice Unit and his "Up In The Woods" CD (which I acquired on the recommendation of a fellow Cafe member), I tend to agree that he was fortunate enough to find what seems to be the perfect instrument for him.
My question is: what other artists have that strong of a connection with one particular instrument? I'll kick the discussion off with a few easy ones off the top of my head:
Bill Monroe and his '23 Loar-signed Gibson F-5
Tony Rice and his "Antique" 1935 Martin D-28
David Rawlings and his 1935 Epiphone Olympic
