HGH-3T, hard tension, is a hybrid treble classical half set made up of D'Addario's laser sorted clear nylon B/E strings, paired with a Carbon G string. Each set contains a combination of monofilament clear nylon paired with fluorocarbon strings for players who like to combine the bright projecting carbon sound with a more traditional tone of nylon trebles. Each half set contains 3 treble strings in a convenient resealable pouch.
