How to Tune to DADADD (Tremonti)
DADADD is Mark Tremonti's go-to open-D-based tuning. The doubled high D strings ring in a natural chorus that sounds heavenly under clean arpeggios and heavy riffs alike, opening up chord voicings that standard tuning cannot reach.

String Tension & Setup Tips
Recommended Gauge:The low E drops to D, the G up to A, the B up to D and the high E stays D, so the top strings gain some tension — a balanced light set works; ease the high strings up gradually.
