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 similarly to standard pegs, without glue, just by pressing into its place. Self-locking inside the peg, the string does not lose tension. No wear marks on the peg or peg hole (the peg does not thread, thus there is no friction). Climate and humidity do not affect. Consistent design, size, colour and quality. The package contains 4 pegs. Size 1/2-1/4 Ø 12.0 /1:25.
