DR Strings Sunbeams RCA-13

Finally a real set 13-56 of lower tension strings that don’t have thinner G D and A strings. I tune to Eb standard for shredding and hybrid picking style, which is a,atoms for me cos I couldn’t get anywhere near with even Martin Flexible Core 13-56. Sure there’s still some work to do in terms of building strength but a darn sight easier than Martin flex core 13-56 and daddario and elixir of the same gauge and in the same tuning .. and they are super warm rich sounding and bloom in D standard! I’m going to try the 12-54 set in Eb on my 814 next.
Very warm sounding too

Twice the price of Martin MEC13s but if the warmth and tone you expect from a round core string is what you seek then these are the strings for you.
Expensive for everyday use as they are not as durable as hex core strings but for that special guitar or special gig these strings will not disappoint.

Best strings I've ever tried.

There's been a dud string in the past
