Whatever brought you here, curiosity or need, here’s an extensive introduction to guitar slides, what they are, how to buy them, which one is the best, and how to use it. 

What is a Guitar Slide and What is it Used For?

A guitar slide is a guitar technique most likely encountered in the blues genre. This technique typically involves a hard object, such as a wine bottleneck to slide over the strings instead of fingers. Traditionally it was a bottleneck, which evolved into metal pipes. However, nowadays, many other materials are used to make the guitar slide. 

The main result of using a guitar slide is that you can create glissando effects and deep vibratos. The guitar slide has a tubular appearance and is placed on one of your fingers. Then, you pluck the strings while the slide is moved across them, changing the pitch. The main advantage of the guitar slide is that the notes are not fixed in pitch, but can move around from one another, which gives the slide guitar a unique sound. 

How to Choose a Guitar Slide

Before you go out and buy a guitar slide, you need to know what to look for. Here are a few things to keep in mind.

Good Fit

When you choose a guitar slide, you first need to decide which finger you will use. For first-timers, the most common is the ring finger, since you can easily use your middle and pinky fingers to support the weight. On the other hand, you could also consider a slide for your pinky, because you have three other fingers which can be used on chords and fretting. 

In addition to this, the perfect slide should cover the two knuckles of your finger slightly, so it will not fall down and can still be easily used without additional support from pinky and middle fingers. This can be tricky because slides are handmade and all sizes different, especially between manufacturers. However, here is a quick guide to sizing:

Small — Ring size 4–7.5

Medium — Ring size 8–10.5

Large — Ring size 11–13.5

Extra Large — Ring size 14–16


The thickness could be quite crucial for some guitar players. If it is not still obvious, here’s why: the thicker the wall, the less you feel, while a thinner wall will allow you to feel the strings better. Generally, this is important for electric guitar players, and they should go for thinner slides to be able to focus on their effects chain. 


The weight is very important, not only for playability, but also for tone. Heavier weights have warmer tones, more volume and sustain, and less buzzing. A heavy guitar slide should not be the first choice if you are a novice because it might be quite challenging to manipulate, and will not have many benefits. Instead, try to look for lighter ones, especially if you have lighter strings or lower action.

Types of Guitar Slides

The most common guitar slides are made of glass, metal, or ceramic. Here is a short description of each of them:


Historically, the guitar slide was called a ‘bottleneck’ because, well, that was precisely what it was. All slides used to be cut from the top side of the wine bottles. Thus they only existed in glass forms. This offers the shortest sustain and warmest tone, with a smooth glide across the strings. This is also the most fragile of them all, so you might want to pay extra attention when handling. But, no worries! Our list includes a thicker, more impact-resistant model, so you are completely covered. 


These slides can be made of either steel or brass. Compared to the first type, they are significantly heavier and sturdier, with brighter notes and a long sustain, because they are also significantly thicker compared to glass slides. Additionally, and obviously, they are more durable compared to glass. Brass is denser and softer, which results in louder, but darker sounds compared to steel. 


The least common is ceramic. It is not widely used yet because it is one of the newest developments. However, they do exist, and you should know that they are mid-way between the glass and metal slides, in terms of everything: weight, texture, hardness, tone, glide, and sustain. The main drawback is they are extremely sensitive, even compared to glass. 

How to Use a Guitar Slide

So far, you probably have a slight idea which slide might be best for you. Here are instructions on how to use one:

  1. Grab your slide and decide which finger you want to use it on (go for the best fit). 
  2. Tune your guitar for sliding (open tuning).
  3. Mute the string above your slide with your hand
  4. Press the slide directly above your fret.
  5. Pick a note, mute the rest of the strings, press gently with the slide and move up and down (this will make the sliding sound).
  6. Always be gentle, do not press hard; otherwise, the strings will touch the fretboard, and they will make an unpleasant noise. 
  7. Try out different methods, techniques, and sounds to find your best playing style. 


On a final note, this article has introduced you to the world of guitar slides, what they are, what to consider before purchasing, the best ones on the market, and how to use one. Next, it is up to you whether you want to undertake this adventure on not, as it is only for the adventurous souls!
