Machine heads for classical guitar in 70 mm size
The Boston 129-B is designed as a replacement set of machine heads for classical guitar. You get a 3x left and 3x right configuration, matching the usual layout of a classical instrument with nylon strings.
The 70 mm size makes fit an important point when you want to replace existing guitar tuners. The nylon shaft and nickel finish make this a practical and tidy option for a classical guitar.
Boston 129-B design and use
These Boston machine heads are made for classical guitar and therefore aimed at instruments in this specific format. The combination of nylon shaft and nickel finish gives you clear information about both construction and appearance, so you can compare them directly with the set already on your instrument.
If you want to check whether the size matches your guitar, the 70 mm specification is the key detail to start with. At Magna Music, you can also get focused advice from the shop and workshop if needed.
