How Do Guitar Pedals Work + 16 Different Pedal Types Explained


As a guitarist, you probably are looking to extend your guitar’s capabilities by having a vast collection of effects pedals. Jimi Hendrix, often considered as a ‘guitar god,’ was renowned for this hence why his subtle style to this date is still engrained into the American rock culture.


The two effects Hendrix used are the Vox Wah-Wah and Arbiter Fuzz Face, which made his songs a technical masterpiece. If you want to add to your unique sound, taking the time to select the right pedal can really make a difference.


Guitar effects usually come in the form of foot pedal with buttons control knobs as well as switches, which are often positioned on the floor to allow you easy access. These guitar pedals are then prearranged on a custom-made pedalboard.


Consequently, you simply need to kick or step on the pedals using one foot to either disable or enable it through the entire show or song.


Guitar pedals create unique sound effects by manipulating your guitar tones’ sound. Likewise, it assists you in improving the overall sound by helping you adjust your volume, tune your guitar, or get rid of unnecessary noises.


Thus, it enables you to achieve a more polished, overall sound. Pedals work perfectly well with bass, acoustic (with pickup), electric guitars, and others even with keyboards.


How do you use guitar pedals while playing? 

After arranging and connecting your guitar pedals in a manner that produces the sound that you find suitable, you need to start exploring how to use it while playing. Guitar pedals can be used in two main ways, therefore let’s dive into each of these methods.


Effects on demand

This is the most common way you can use your guitar pedal. This system entails you turning the pedals on and off while playing, depending on the sound you want to hear.


For instance, many guitarists when playing solo turn on the wah pedal and turn it off once they are done. In this particular example, you are making use of the wah pedal to create the ‘on-demand’ effect. Whenever it is active, it colors your guitar tone and then goes back to the ‘normal’ guitar tone after it is switched off.


Guitar pedals like the phaser, wah, tuner, booster, or whammy are usually used to create on-demand effects. Therefore, you should think of this as a combination of your ‘normal’ tone and ‘effects’ tone.


Tom Morello is a good example of a guitarist who makes use of on-demand effects, and he combines pedals effects in his solo to produce a peculiar and wacky sound. He does this while using a ‘normal’ tone, which he does not use pedals completely.


In his solo song, the Rage Against the Machine, Tom switches on both the Delay and whammy pedal and later turns them off once he finishes his solo. This is an ideal example of how you can on-demand effects and how they make the subsequent sounds enjoyable.


Always-On Pedals

Guitarists usually overlook this method of using guitar pedals. Guitar pedals are often seen as effects that you can switch on and off while the song is playing. Nevertheless, there also is a different way of always having the pedal turned on.


Consequently, your guitar’s ‘normal’ tone is continually enhanced by the pedal, and this is an excellent way of creating a distinctive tone that cannot be produced by a regular guitar amp.


For instance, if you are playing surf-rock and like the sound produced by the spring reverb, you can incorporate it to your rig and have it on throughput your song or show. Doing this makes the reverb a normal tone produced by your guitar.


Despite having the option to switch it off anytime, you should always leave it on to add personality to your tone.


Another excellent example of this is most guitarists always having their compressor pedals on, and it helps equalize your tone’s signal, thereby giving it a more consistent volume level.


Additionally, this compressor can be used in enhancing your tone, so having it on all the time makes it a regular part of your exceptional tone. An excellent example of a guitarist who did this is Eddie Van Halen with this ‘brown sound’ and he at all times had his on-guitar pedals on to create this unique sound.


How Do You Plug In A Guitar Pedal? 

After you buy your guitar pedal, the first thing to do is connect it correctly to the amp and guitar, which is extremely easy, but you need to have a couple of things. When you’re not using a guitar pedal, you plug your guitar directly into your amp’s input jack.


However, adding a guitar pedal changes the way you are required to plug in your guitar.


To do this, you require two guitar cables for every guitar pedal your purchase. One of the wires you will plug into the pedal’s output and the other to the input of the pedal.


Most of the guitar pedals label the output and input jacks, but the standard feature is for output to be positioned on the pedal’s left side, whereas the input is placed on the right side. In case you only have one pedal, all you need are two cables for the whole rig.


Now, plug your guitar into your pedal’s input jack and the other cable into the pedal’s output, which you subsequently connect to your guitar amp input. The majority of amps have guitar inputs positioned at the front, whereas others are on back or top.


Additionally, it is advisable that the cables you buy for both the output and input cables for the guitar pedals are long, for example, at least 3m/10ft. Having longer cables allows you to place your guitar pedal away from the amp if you prefer it that way.


For instance, while performing on stage, your amp can be positioned at the back of the stage, whereas the pedal is at the front. Therefore, it is always recommended to own a spare long cable if you want to have extra room to move.


How Do You Connect Pedals?  

If you are looking to connect over one guitar pedal, you will require additional cables. Thus, if you want to use two guitar pedals, you will need a total of three wires. One of the cables will be to connect the pedals, one to join the guitar, and the other to connect to the amp.


You should buy ‘patch cables’ if you want to connect guitar pedals, which are designed specifically for connecting guitar pedals. Thanks to patch cables, your pedalboard will always look tidy and nice.


Therefore, the more guitar pedals you buy, the more you need additional patch cables to ensure your pedalboard is tidy.


From the figure above, you can see you will require three patch cables to connect your rig to two pedals. These are one short patch cable in the center to connect together two guitar pedals and two long cables.


If you ever need to add another pedal, you will have to buy another patch cable that comes in a pack of four to six cables for each extra pedal.


Guitar Effects Pedals That You Must Have 

There are numerous types of guitar pedals on the market nowadays. Therefore, making which pedal you should buy can be an overwhelming decision, especially if this is the first guitar pedal you are buying.
