EXP74, D'Addario's best selling coated mandolin set, is the EXP coated version of the standard J74 set played by the likes of David Grisman and Ricky Skaggs. Warm and bright phosphor bronze tone with the optimal blend of tight playing tension and strong projection. Loopend construction for universal fit. D'Addario EXPs are the most natural-sounding, longest-lasting coated strings available. EXP Coated Technology starts with the highest quality wrap wire materials, precision drawn and micro-coated on our advanced proprietary machinery. Strings are then wound normally, delivering tone and feel identical to D'Addario's world renowned mandolin strings, with a minimum of 4 times more life. You won't believe they are coated!
