“Lots of Zzing when fresh… still long lasting without losing tone and comfort”
“They don’t eat your frets” — a repeated claim in DR’s own description
Feel & Playability
Round core construction gives a softer, more flexible feel than hex core stainless strings
Suitable for slap, pop, and articulate fingerstyle; one reviewer highlights them as ideal for bright slap tones

Stainless steel wrap for brightness and durability
