This is a set of Jin Lu silk strings that I have had the opportunity to borrow for my research. Unfortunately string 4 was missing from the set, but the set has still provided very valuable data for my study. This set seemed very little played, and is one of the cheaper sets of silk strings out there. However, the strings felt rougher than all of the other silk sets I have tested, and currently (in my opinion), they are my least favorite set in regards to tone and playability for silk strings on my personal qin.
