Looking for some classic guitar tones for my Fender Telecaster Standard USA i came across these strings. Being a fan of other DR string series, i wanted to find warmer tones for this extremely bright sounding guitar. I must say i love these strings. The tone is strong, warm, rich. I was not so much disturbed with these strings being quiet hard, as i usually used heavier gauges, but perhaps it's a good thing to consider- if you want to use some bluesy string bending it's best to use some lighter gauge. As i said, not a problem if you are used of harder strings. But i put the sound before all else, so these strings deliver that brilliantly. The only thing i really don't like about them is that they break easily. I went so far to buy new bridge saddle, thinking it's the guitar's fault but the problem is still there... So all things considered i still use them and don't see a substitute between all the strings i've tried, and i really tried a lot of them.
