The creation or repair of a fine stringed instrument is more than bending and carving materials into shapes that have been standardized over time.
"Any good craftsman can set up an instrument according to the norms," says Peterson. "But adjusting and bringing out the best nature of the instruments—according to the nature of the musicians who will be playing them—is where the personal, artistic touch comes in.
"Lots of musicians find it refreshing to find someone who wants to hear their side of the story—someone who wants to find out how they play, what they are after and who can tell them whether their instrument can achieve what they are after. People will travel 1,000 miles for 10 minutes of good information. It's worth it to them."
World of Strings' current expansion is being accompanied by a musical celebration Saturday from 11 a.m. to 5 p.m. A variety of the shop's accomplished customers will perform in such genres as classical, bluegrass, flamenco and jazz. Baldwin, 32 years after his first visit to World of Strings, will perform Brazilian jazz at 3 p.m.
"We're calling it a concert, I guess," says Peterson, "but it's just friends coming in and playing. That's not much different than usual. A lot of these same people come in and hang out and play all the time anyway."
