The Oasis GPX+ GX-1123NT set of classical guitar strings consists of long-life normal tension carbon trebles. The GX-1123NT set includes high endurance 1st string.
The Oasis GPX+ trebles are designed to withstand even the most punishing playing styles. Now including a new high endurance 1st string, they maintain beautiful tone and sustain that have made GPX+ strings so popular. Easy on the left hand, GPX+ strings have the same tension as nylon, thanks to the PVDF fluorocarbon material which is 80% denser than nylon. The brilliance of these fluorocarbon (carbon treble) strings does not rely on the typical stiff hard action of other carbon trebles.
