The Oasis GPX+ HT/NT GX-1000N set of classical guitar strings consists of long-life high tension carbon trebles and normal tension Sostenuto basses. The GX-1000N set includes high endurance 1st string.
The Oasis GPX+ strings 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.
GPX+ carbon treble sets are matched with Sostenuto bass strings. Sostenuto basses were developed by Oasis for the discerning classical guitarist who, above all, desires a lyrical and powerful sound, with prolonged sustain. The strings settle in quickly and have improved durability. Sostenuto bass strings come in three different tensions: normal, medium and high. They are wrapped in tarnish resistant poly bags.
