It is a pretty small shop of of I20 and Little Road behind the Hooters sort of.Tell me about this 'String Connection' that you speak of. I've lived in Arlington a long time and don't recognize the name.
The do lessons and focus on violins, bluegrass, and acoustics. The owner Don has worked in many shops around town doing repairs for others. He does pretty good work. He gets swamped and can take a few days to a week. But that's better than Charlie's over in Dallas. They are running months behind for setups.
Here is a link.
