The first tuning fork was invented by John Shore in 1711 to tune musical instruments. Tuning Forks are still being used to tune instruments such as pianos, guitars and more over 300 years later due to their accuracy and simplicity to use.
RAGG's musical tuning fork design is their famous John Walker. Used all over the world, the small steel fork comes in a blued or 9ct gold plated finish and is tuned to a range of frequencies, with the most popular being the A440Hz Standard Orchestra Pitch.
