What Is a Synthesizer Pedal for Guitar?

A guitar synthesizer first, is an electronic instrument, using either analog or digital processing to reproduce the sounds made. A guitar synthesizer pedal is an effect processor through which guitarists can use their guitars to copy or emulate the sound produced by the synthesizer. In simpler terms, a synth pedal means a traditional stompbox through which you can play the synthesizer, using notes you play on your instrument.

Choosing the Right Guitar Synth

The popularity of guitar synthesizers has skyrocketed over the past few years. The reason is that a guitar synth allows musicians to play both synth and guitar and even blend them. There are many pedal guitar synths on the market, which makes the process of choosing one very confusing.

There are some factors that you should consider to make an informed decision.

Durability and Warranty

A multi-effect synthesizer is a piece of equipment that you’ll use a lot. Carefully consider the ability of each option to withstand the test of time. Additionally, once you settle on one of the durable pedal guitar synthesizers, examine their warranties and check how long the item will be covered. Synthesizers can be a big investment, and you don’t want to lose yours if something goes wrong shortly after receipt.

Size

Size is an important but often overlooked factor to consider, especially when shopping online. A synthesizer that’s too large will not be very portable. You want to make sure that the guitar synth you purchase will be comfortable and small enough to carry around from gig to gig. You also don’t want to have to struggle to find space for your synthesizer at home.

Ease of Use

Some guitar interfaces come packed with many amazing features. However, getting to know how to maneuver your way through the pedal synthesizer could be hard. Before purchasing, always take note of the interface and make sure you’ll be able to navigate the controls.

Easy to read user manuals, how-to videos, and online support for your device would be a helpful bonus. If you’re still new to guitar, you might not want to go for an advanced model with plenty of effects straight away. 

Type of Effects

Every kind of synthesizer will come with a variety of options, and some have an effects loop. The finest types of effects have much to do with preference. Before spending cash on a synthesizer, take time to think about your music, why you want a pedal synthesizer, and what you want it to do. After that self-evaluation, it should narrow down your choice of pedal synthesizers to only those that offer the guitar effects you want.

Overdrive and Distortion

Overdrive is a naturally occurring distortion that takes place once you have plugged in an amp, but a guitar synthesizer amplifies that throaty sound your ax is creating. On the other hand, distortion will offer a sweet smooth sound that’s a blend of notes, creating a cool different sound level. Consider the overdrive and distortion of any unit before investing in one.

EQ

EQ refers to equalization, which is when where the balance between frequency within an electronic signal is adjusted. An equalizing gadget is known as an equalizer; its job is to either strengthen or weaken energy in specific frequency ranges.

Your EQ will boost the sound aspects, which limits the effects of creating a unique sound profile. For instance, you can raise your treble to create an amazing bell; this goes a long way to boost the bass, creating an awesome bass guitar riff.

The equalizer in the synth you choose is one of the most important features.

Sound Conditioning

A synthesizer with sound conditioning allows you to control your volume without having to stop everything to manually adjust it with the knob that’s on the guitar. The strength behind your sound is referred to as gain. While performing, especially solo, you want to have control over your volume and gain, too, without having to pause your performance to do so.

If you’re a solo performer, it’s highly advisable that you only consider synth pedals that allow for sound conditioning.

Compatibility

Some synthesizers are compatible with multiple instruments. If you’re a musician with a variety of electronic instruments in your repertoire, you might want to select a model that you can use with all of them. 

Advantages of Using a Guitar Synthesizer Pedal

A guitar synth pedal is an effect processor; it allows you to emulate sounds with the synthesizer using your guitar. 

Using a synth pedal allows you to expand your sonic palette while creating distinctive tones. Each pedal will usually have a different emulation process; some utilize analog circuits, while others might be using digital computer chips and algorithms.

After activating the guitar effects unit, the synth pedal takes an output signal from your guitar and begins to change your overall sound.

Versatile Performance 

The processing units are usable in both live performance settings and in-studio recording sessions too. That means you can replicate your unique sound creations wherever you play.

If you want, you can also play the synthesizer alone. Combined with the many tones you can achieve, you have plenty of options to experiment musically.

Seamless Playing 

One of the issues with earlier guitar synthesizers is that they would lag, which would create discord during performances. Newer, more advanced models typically don’t have this issue.

User-Friendly

Synthesizers are a simpler alternative to a keyboard as they’re easier to handle. At the same time, they usually offer a wider range of sounds than a keyboard does. 

You don’t require a special set of skills to use a synthesizer either—it’s less effort to learn to use one of these gadgets than to pick up a new instrument to accompany your guitar.

Almost any guitar is compatible with the average synthesizer, too. You won’t have to worry about upgrading your current ax to benefit.

Why Use Hardware Synthesizers and When Can I Use Software?

Some view hardware as an outdated means since every sound you seek is probably available as a sample somewhere. So why really, should you purchase any of the listed pedal synthesizers that will take up space when you can access the same through software?

The biggest advantage of using software is your ability to tweak the knobs. As underestimated as it may be, that direct connection with the sounds you’re making pushes you to come up with a variety of ways to create sounds, something that clicks on a mouse is less likely to inspire. 

Sound quality through hardware synthesizer effects is definitely better and more natural-sounding; this is not just for famous pedal synthesizers and equalizers. Even the cheapest pedals bring their own authentic sounds to the table. 

Hardware actually adds life to your production. A perfectly tuned and edited vocal track is great, but they’re often less impressive than manually created sounds. Variations that come with using hardware, and even the little flaws that are inevitable, often make you sound more human and relatable. Not only does the use of hardware aid you in breathing life and character into your productions, but it’s also easy to implement in a modern production studio.

All in all, the sound is a matter of preference; some guitarists might find classic synth sounds to be outdated. However, a bigger chunk of players don’t, and interestingly a lot of producers seek to re-use sounds from the 80s. Even traditional rock bands, such as glam metal band Mötley Crüe, tried synthesizers in later albums. Since you can input the sounds after creating them, you can even create a mix of both worlds with the use of synths for some part of the sounds and some touch-ups for the software end.

Conclusion

Our top nine feature some of the finest guitar synth pedals, and you can’t go wrong with any of them.
