Your Guide to Buying Machine Heads for Your Guitar

Machine heads play the vital role of enabling the guitarist to tune the instrument, and few things are more frustrating than having machine heads that do not perform well. The reasons for purchasing new or used machine heads are varied. Machine heads can be damaged or simply wear out. Some guitarists are keen to upgrade their guitars to improve both looks and performance, and some enthusiasts may be building a new guitar from scratch. When replacing machine heads, it is sometimes possible to find an exact match, particularly for a well-known brand or model of guitar, but often it is easier to replace all the heads at once. Keeping spare matching machine heads on hand is also a sensible idea for guitarists who may need to change heads often. Spare parts such as screws, bushings, and buttons can also be purchased separately.

Types of Machine Heads

Essentially, any guitar will have one of three types of machine head. Classical, nylon stringed guitars have a standard-sized machine head that is usually to be found complete with a screw on plate. Acoustic, and some electric, guitars typically have bolt on machine heads while other electric and bass guitars may have bushing based machine heads. Within these parameters there are many options available.

Classical Guitar Machine Heads

All adult sized classical guitars will accept the standard size of machine heads. Machine heads for classical guitars typically have a relatively ornate screw on plate and this is the easiest way to replace either one side or the other. Pegs that slot into the neck are also usually included as part of the unit. It is usual for the machine heads to be purchased as a set as different heads on each side can look a little strange. Heads can also be purchased individually and if choosing this option it is probably worth buying an extra set for future use.

Plastic or resin tuning pegs crown style

Usually finished in ivory or cream. Plate attachments in a variety of finishes.

Plastic or resin tuning pegs ornate butterfly style

Normally available in ivory or cream with ornate plate.

Chrome tuning pegs with chrome cogs/inserts and metalwork

Usually a choice for Spanish nylon stringed guitars although some classical guitarists also appreciate the aesthetics.

Nickel-plated metalwork

Available with plastic, resin, or plated tuning pegs.

Chrome-plated metalwork

Usually with crown style tuning pegs.

Gold-plated metalwork

Tuning pegs may be gold plated or ivory or white plain or pearlescent. Metalwork is usually ornate carved style.

Single screw in heads

Rather than being on a set of three, these heads are attached individually. Usually sold in sets of six but can occasionally be found individually. A variety of designs and finishes are readily available including vintage.

Machine Heads for Acoustic Guitars

Like classical guitar heads, machine heads for acoustic guitars come in standard fittings of 3 per side or as single heads. Some guitarists may choose to opt for a specialist brand, such as Fender, or search for machine heads specifically made for a particular brand like Gibson or Martin. This is certainly a valid option although there are many machine heads that will suit these guitars in a range of prices and quality.

3 per side on chrome-plated metalwork

Usually with resin pegs in white, ivory, or pearl. Black tuning pegs are also available. Occasionally genuine ivory pegs may be found. Chrome pegs may also be used.

3 per side with gold-plated metalwork

Pegs may be resin, plastic, or metal plated.

Chrome with coloured buttons

Recommended for the more flamboyant guitarist. Purchase in sets of one colour or individually for a rainbow of creative flamboyance.

Individual bushing based heads

Available in chrome, gold, ivory, and other finishes. Chrome is probably the most common available with standard tuning pegs, but other colours and styles can be found including vintage heads for the serious collector.

Individual bolt on heads

As with bushing based heads many styles and finishes are available.

Spare parts

Useful for replacing damaged heads. Choose to match machine head.

Machine Heads for Electric Guitars

Whether nickel, black, chrome, or gold, machine heads for electric guitars are readily available to suit any budget and any make or model of electric guitar. Both bolt on and bushing heads can be found in a large range of materials. Quality can vary but machine heads can be found to suit the most modest budget or the most serious guitar collector. Machine heads are normally sold in sets of six. While many machine heads look attractive, it is also important to ensure that the internal gear is of good quality for durability and high performance.
