I just changed my stings to Dr Sunbeams. I can't say they sound any better than the EB Slinkys I took off, but they are new so I'll have to give them time to settle. I've been a die hard Slinky user, and have tried most of the other DR strings, but always ended back with the Slinky. There just something about them when they mellow. I will say the Sunbeams feel very smooth, and I'll have to get use to the 125 B sting where as the Slinky has a 135 B. Can anyone tell me about the sound when the Sunbeams mellow?
I personally use the Sunbeams for the tone I get when they mellow. I'm not the greatest fan of them new (but then again, I'm not much of a fan of any new tone on any string).
To me, the Sunbeams carry a nice round and punchy tone when they mellow that just seems to fit for me- both fingerstyle and with a pick. They've got a smooth attack, a nice punch, even tonal response, and overall roundness that is slightly akin to a flatwound, but with more roundwound character. And they still maintain a little bit of snarl or bark that you get with a standard roundwound.
