The guitar saddle is a crucial component of the guitar, usually found on the bridge, where it plays a vital role in the instrument’s sound and playability. Crafted from materials like bone, plastic, or metal, the saddle supports the guitar strings at a precise height, ensuring optimal string tension and spacing. Its positioning and quality significantly influence the guitar’s intonation, affecting how accurately the instrument stays in tune across the fretboard.
A well-made and properly adjusted saddle helps produce a clearer, more resonant tone, while also contributing to the comfort and ease of playing. This small but essential part thus holds great significance in both acoustic and electric guitars, underlining its importance in guitar craftsmanship and performance.
Introduction to Guitar Saddles
The guitar saddle is a piece of bone or plastic attached to the bridge that lifts the strings to the desired height and transfers vibration through the bridge to the soundboard. The height of the saddle raises or lowers “action” – the distance between your strings and the fingerboard.
A beginner guitarist may not notice much of a tonal difference. However, intermediate to advanced guitarists will typically hear a difference. Bone saddles almost always sound better than the inexpensive plastic saddles used in less expensive guitars.
Types of Guitar Saddles
There are five main types of guitar saddles:
- Drop-In: these saddles are typically not glued in, meaning you’re free to take them out and lower them should you wish (lowering is done by cutting or filing away material from the bottom).
- Long Set: a variation on the drop-in, the long set saddle is, in contrast, glued into place and extends into the wings of the bridge to avoid movement.
- Straight/Uncompensated: a straight saddle that doesn’t have any grooves and is flat across the crown (the crown is the point on the top of the saddle where it touches the strings)
- Compensated: as strings are pressed down on the fretboard, the various thicknesses of the strings affect the downward distance the string travels before it hits the fingered fret.
- This variability can throw off intonation for the higher strings. A compensated saddle with an elevation for high E and B strings helps normalize the effective string length and helps the guitar sound in tune with notes played higher up the fretboard.
Installing a Guitar Saddle
This can be a remarkably easy process. Start by removing the strings and bridge pins, then, after removing your strings, the saddle should just come out of the slot without any trouble. If it does get stuck, or it’s glued in, you definitely want to talk to a guitar tech or luthier. You don’t want to pry it out because it could rip up some of the bridge.
The next step is seeing how the saddle blank fits into the bridge slot. If you find yours isn’t fitting, you don’t want to force it in. What you can do is take a piece of sandpaper, put it on a flat surface, and use that to get the right thickness.
Adjusting the Guitar Saddle
You can go further and adjust the height of each individual saddle with the same method.
Take the old saddle and lay it across the top of the new saddle. Line them up as best you can, and then draw a line with a nice, sharp pencil. Right there you will know how much height you need to take off to get the same action with your new saddle.
Use your sandpaper to get the right height. When you get close to the line you have drawn, take two blocks and sand the piece to get a nice, straight, right angle on the bottom of the saddle.
Common Issues with Guitar Saddles
One of the most common and most noticeable problems is poor tone. When a saddle leans forward, the bottom does not make good contact with the bridge, which results in poor string energy transmission to the guitar top, and poor tone.
That being said, there is no need to replace a guitar’s saddle unless it has been fractured or otherwise has been rendered unusable. Even a saddle that has been shaved too low to properly position the strings or making the action too low can often be shimmed to bring it back into proper position.
Impact of the Saddle on Guitar Tone
Shifting from a plastic to a bone saddle will typically produce a fuller tone that many acoustic guitarists prefer, but it depends on individual tastes and specific guitars.
However, compared to Tusq saddles, bone does not necessarily produce a better tone, but does a different one. Generally speaking, bone produces a warmer and fuller tone, whereas Tusq produces a brighter and cleaner tone. It depends on the individual player and specific guitar as to which saddle material is preferred. Below is a further discussion of the common guitar saddle types.
The Saddle’s Role in Guitar Action
The middle point between the nut and the saddle is the 12th fret. If we measure our string action at the 12th fret, we can know that it’s half the height of the upright part of the triangle, i.e. the saddle. Put it another way, the saddle height is two times the 12th fret action.
Given this and the fact that the bridge is likely one of the single most defining contributors to guitar action (as well as the notion that the saddles are the dictators of the bridge), it’s not hard to see how the saddles come to wholly dictate this aspect of the guitar.
Choosing the Right Saddle for Your Guitar
Bone produces a warm, rich tone that many people seek with acoustic guitars, particularly with Martin guitars. Most higher-end guitars come with bone saddles, which leads many to believe that bone is necessarily the best saddle material.
That being said, some might not be able to spare this expense or might prefer to try something different like a Tusq saddle which nowadays gives bone saddles a run for their money.
An acoustic guitar’s saddle is one of the most important parts of the guitar. The guitar’s action, radius, intonation, and tone are directly directly influenced by the saddle, so it’s important that it’s perfect.
Hopefully, you can now see just how important the saddle is and how it has such a direct impact on so many other parts and aspects of a guitar’s overall tone and feel.
FAQs Guitar Saddle
The guitar saddle is a piece of bone or plastic attached to the bridge that lifts the strings to the desired height and transfers vibration through the bridge to the soundboard. The height of the saddle raises or lowers the action.
Without the saddle the string is suspended only at the nut and tuning is disabled. There is also damage risk to the bridge and plate if the strings are tightened. Normally the saddle rides in a snug slot and is never removed. A loose saddle may fall from its slot if all strings are removed.
People often use the two terms interchangeably, but they are distinct parts. The bridge is the wooden piece that holds the saddle and bridge pins in place on the guitar top. However, the saddle is the thin piece of plastic or bone upon which the strings rest.
