Stable, Accurate, Clear. DDT Strings go right in tune and lock in. The first thing you will notice is that these strings go right into tune and lock in. Players say they are "so stable it is almost eerie." Now you can stand and deliver in tune notes at lower pitch that are clean and clear. Expect more and get more. Change tunings and be surprised how DDTs lock right in. Be surprised how little adjustments you make. DDTs deliver far more than just heavy gauges. Drop with confidence, drop with accuracy. DDTs maintain their intonation at lower tunings far better than any other string we have ever played or heard. Designed over a two year build and test period to answer the needs of the dark side.
