The wonderful thing about art is the many ways it can produce pleasure: you can listen to beautiful music, you can learn how to play it, you can dance to it, and you can even collect the instruments that make it. If you belong to this last group, you’ll be very happy to learn about this site, home for a devoted collector and seller of vintage guitars and string instruments.
Mr. Gruhn lives and has his music shop in Nashville, but users from around the world can discover his impressive inventory through this site by taking the video tour; and though you can also browse the instruments themselves, note that you’ll have to open each link individually, which seems rather uncomfortable if compared to a thumbnail mosaic or slideshow, which would be just great for musical instrument lovers who might or not be interested in buying but in taking a look at the instruments themselves. Note that you can’t buy instruments directly from the site, but you can email the store about how to process your purchase. The company also offers repair and appraisal services, which you can contact using the form online; for a fee they even offer to appraise your instrument if you send them some pictures and a description. Also interesting is the fact that you can mail them in with your request for a particular instrument or model you can’t find in the site, and they promise to do their best at trying to get it for you. While you wait, it could be a good idea to take a look at the library of articles by Mr. Gruhn which will walk you through the most relevant items in his collection and explain the most salient features of instruments and models, so you are sure to learn about really interesting things in the process.
