Very easy, fast, and precise tuning. Transmission ratio 8.5:1, compared to a standard peg. Made from High-Tech composite material and lightweight alloy. The installation of the pegs is done like standard pegs, without glue, just by pressing into place. Self-locking inside the peg, the string does not lose tension. No signs of wear on the peg or peg hole (the peg does not thread, therefore there is no friction). Climate and humidity do not affect. Design, size, colour, and consistent quality. The package contains 4 pegs. Size 4/4-7/8 Ø 14.0 /1:25.
