There are a LOT of sites online that concentrate on stringed instruments. There are amazing sites that are full of useful information. There are new, poor sites that have bad information or, even worse, are some "learning quick" scam. In the middle you'll find all sorts of weird, funny, and strange sites.
The goal with our "Top 50" lists is to give you an idea which sites we read (when we're not hanging out here!). The sites that have great information or teach high quality lessons. Hopefully, by looking through our lists, you'll save yourself the trouble and wasted time that you'd suffer going to some of the bad sites.
