The DR Strings Pure Blues 11-50 are a set of electric guitar strings that I recently purchased to string up my Schecter Ultra III guitar. I hadn't used these strings before getting them as the guy at the guitar store recommended trying them out as a lot of people there were digging them. I don't get too fussy when it comes to strings, but I do like 11 gauge strings as these are. I figured I'd try them out and I'm glad I did as I'll definitely be buying a few more pairs of these for the same guitar in the future. While the Ultra III isn't my main axe, it was in dire need of string replacement and figured it would be a good opportunity to try some new strings. They don't cost much and are certainly comparable to other electric guitar strings, so price shouldn't be very much of a factor here. It was easy enough to string up my guitar with the DR Strings Pure Blues 11-50's as they are standard in every sense of the word. I was immediately happy with the way they were feeling as they felt sturdy while still easily playable. They sound good to as my Schecter Ultra III sounds as good as it has sounded. I don't know exactly why these are deemed "blues" strings as they were certainly work for other types of music as I mostly play rock. I'm not sure that the strings would be the right fit for my main guitar which is a Fender Jazzmaster as I like lighter strings on them, but next time I need a change I'm going to try them anyway to see how it works. If you're looking for a new set of strings for your electric guitar, go out and try the DR Strings Pure Blues and I think you'll be pretty satisfied with them.
