DR DDT-12 Extra Heavy Guitar Strings 12-60
 
DDT™ Electric Guitar Strings maintain their intonation at even the lowest tunings thanks to DR’s Coated Core Technology™ (CCT™).  A coated hexagonal core wire locks the nickel-plated steel wrap wire in place to increase stability at any tension. Now you can deliver notes at lower pitch that are clean, clear and in tune. Change tunings and you’ll be surprised how easily DDT's lock right in and stay there.
