just put on a set of 50-100s on my p-style washburn. while tuning up on the g-string, the o-ring in the tuning peg popped right off. the d-string really stands out from the others. it sounds nearly as bright as a roundwound, imo, especially when playing with a pick. the e and the a sound "dull" in comparison. i wish there were more string-to-string consistency. i probably will not buy another set of these strings.
