Description

The clear nylon trebles are laser-selected and measured to ensure consistency and controlled playing tension.
Pro-Arté basses are wound using silver-plated copper on a multi-filament nylon core using digitally controlled winding systems.
Available as Light, Normal, Hard and Extra-Hard tension sets of 6; in 3 full set multipacks; in bass only sets in different tensions; in treble only sets in different tensions; and in hybrid treble sets with a carbon g3 string in different tensions.
