Over decades of player feedback, the BOSS SY-1000 synthesizer pedal for guitar and bass has been improved. It has three different synthesizer instrument engines that may all be used at the same time to create deep and rich musical patterns. You can use Roland’s GK pickup for the most precise pitch tracking and per-string parameter manipulation, or you can plug your instrument into a 1/4′′ jack. An effects loop, multi-effects, instrument modeling, external control inputs, and freely assignable footswitches are also included.

BOSS’s guitar/bass synth pedal is highly strong and versatile. It has a new sound engine with 32-bit/48kHz sound quality, which is powered by bespoke DSP. There is no latency or other concerns with the tracking. This unit allows you to control three instruments at once, ranging from synth leads and pads to bass and more, offering you a lot of creative freedom and flexibility. The BOSS SY-1000 has adjustable footswitches and assignable outputs, making it simple to break up your signal flow way you choose. For a wide range of audio textures, combine this unit with the GK pickup (available separately) and your instrument’s 1/4′′ output. The GK pickup provides ultra-precise pitch tracking for synth sounds, while the 1/4′′ output informs the envelope shape and response of the synth.

This gadget, when combined with a GK pickup, allows you fast access to alternate tuning for your guitar or bass. Two 16-step sequencers are included in the Dynamic Synth engine, allowing you to add additional levels of movement to your synth patches. With 13 different envelope curves to explore, each step of each sequencer may regulate pitch, filter knob, and amplitude separately. You can utilize this to get musical results in a subtle way or go all out if necessary.

The SY-1000 pedal includes two extra synth instruments in addition to the Dynamic Synth engine. The OSC Synth is a classic analog synth with a wide range of filter settings, a flexible ADSR envelope, and excellent sound quality. The GR-300 synth engine contains an accurate replica of the vintage Roland GR-300 to delve into the renowned sound of ’80s guitar synths. BOSS SY-1000 is the best Synth pedal in 2023.

Electro-Harmonix Synth9

Electro-Harmonix SYNTH9 Synthesizer Machine Pedal
  • 9 presets that were created to emulate many of the most popular synthesizer...
  • Works on guitar or bass without modifications, special pickups or MIDI...
  • The SYNTH9’s usable tracking range extends up to about the 23rd fret on...

With the Electro-Harmonix Synth 9 Synthesizer Machine pedal, you can make classic synthesiser sounds with your guitar or bass signal. In classic EHX form, you can simply plug this device into your pedalboard and use it as any other effects pedal. Nine presets allow you to access some of the most famous synth sounds from the 1970s and 1980s.

The name “Synth 9” comes from the fact that it features nine basic presets, each of which may be modified to taste using the CTRL 1 and CTRL 2 knobs. Each has its own set of parameters to tweak, giving you an even wider range of alternatives that aren’t immediately apparent. This flexible, durable pedal does it all and does it well, from pop lead voicings to bass pads.

It comes with the following 9 patches, which provide you a lot of options and versatility. The obxn, for example, is a replica of the fat-sounding oberheim ob-x. The profit v, a recreation of the classic prophet-5 synth, follows. The vibe synth is a polyphonic synthesizer with decreasing harmonic content and vibrato that comes next. The mini mood is a big-sounding moog-inspired synthesizer that combines a portamento and a non-portamento synth (the blend is controlled via the volume knob). The ehx mini, on the other hand, is a recreation of the legendary electro-harmonix mini synth. The solo synth is a fuzz-synth preset that combines a synth oscillator with a fuzz square wave guitar to create a single severe synth tone. Following that, the mini moog and taurus bass pedals inspired the mood bass. The string synth, a recreation of an arp string synth, comes next. Last but not least, the poly vi is a synthesizer based on the sumptuous korg polysix.

For guitar and bass, the Synth9 is a superb polyphonic synthesizer pedal. It tracks well with guitar and works well with bass, but the bottom strings of a conventional bass may be a little shaky. There are 9 patches available for Synth9. The Electro-Harmonix Synth 9 pedal, with its exceptionally wide playing range, enables excellent tracking, making it our top option for this list.

That’s what the EHX Synth 9 Synthesizer Machine, which has been used by professionals such as Peter Gabriel and P-Funk, brings to the table. I prefer their other pedal in this list for pads and ambience. This is one of the best guitar synthesizer pedals.

Earthquaker Devices Data Corrupter

Earthquaker Devices is a fascinating pedal company that produces some of the best and most inventive pedals on the market. The easiest way to characterize this pedal is as a fuzz synth, however it can also produce non-fuzzy tones. The Data Corruptor obliterates your guitar sound and replaces it with a fantastic square wave fuzz.

This three-voice Modulated Monophonic Phase-Locked Loop Harmonizer pushes your tone to the limit, insisting on further modulating your sound to create strange yet delightful fuzzy synths. The pedal has a sci-fi feel to it thanks to a frequency modulator, but it’s still very experimental.

If that wasn’t enough, you can also utilize the subharmonic switch to activate various harmonics and octaves, which you can modify until you’re satisfied. Earthquaker Devices manufactures their pedals one at a time using an all-analog signal route and high-quality components, which we believe completely justifies their premium price tag of one of the best guitar synth pedals.

Buying Guide Synth Pedal for Guitar

Selecting a synth pedal that aligns with your musical goals can be a game-changer for your sound. This buying guide aims to help you navigate through the key factors to consider when purchasing a synth pedal.

Sound Capabilities

Different synth pedals offer varied sound capabilities. Some focus on reproducing classic analog synth sounds, while others provide a broad range of digital synth tones. Consider what kind of sounds you wish to incorporate into your music. If you’re after a specific type of synth sound, look for a pedal that specializes in that area.

Interface and Usability

The interface and usability of a synth pedal can significantly impact your experience. Some pedals present a simple interface with a few knobs, making them easy to use but potentially limiting in terms of sound shaping. Others might offer more complex controls, including knobs, switches, and even digital screens, allowing for more extensive sound customization.

Tracking Quality

The quality of a synth pedal’s tracking—how well it follows your playing—can influence how useful and enjoyable it is to play. Good tracking should feel responsive and accurate, without noticeable latency. Some modern synth pedals feature advanced tracking technology that can even handle bends, slides, and vibrato.


Synth pedals come in a wide range of prices, with budget models offering basic features and premium units providing advanced capabilities. While higher-priced pedals often offer more features and higher quality sounds, there are also many affordable synth pedals that deliver great performance. It’s important to set a budget and find a pedal that offers the best balance of price and features for your needs.

Presets and Programmability

Some synth pedals allow you to save and recall presets, which can be a huge advantage if you want to switch between different sounds quickly. If you like to experiment and create your own unique sounds, look for a pedal with programmability features.

Frequently Asked Questions

How does a Guitar Synth Pedal work?

A guitar synthesizer manipulates a normal guitar signal in ways that nature never intended. They can be used to create wholly new auditory experiences or to try to replicate existing instruments by using devices like LFOs, filters, and wave generators.

Many of these features are packed into one handy unit that fits comfortably on most pedalboards with guitar synth pedals. Because they aren’t usually ‘full function,’ you may want to try a few various models to discover which ones will make the noises you need/want/desire.

If you want to imitate the sounds of other instruments, you should keep your expectations realistic about what a synth pedal can do. Analog waveforms are incredibly difficult to understand. It’s possible that you won’t be able to make your guitar sound exactly like a horn section.

What features should a Guitar Synth Pedal have?

A way to regulate the mix of dry (guitar) and wet (after effects) signals is an important element that every successful model should include. On their own, some synth tones may be a little too strong. Having the opportunity to add some dry signal to smooth things out could be the solution.

What constitutes a “good” feature is largely determined by the player and what he or she wishes to accomplish. Some people prefer a device like the Boss SY-1 Synthesizer, which has a lot of presets and little tweakability, while others prefer the Source Audio C4, which has an offline editor for a lot of deep editing.

Spending time with a few models to see which technique works is one of the finest ways to decide. There’s nothing wrong with examining your alternatives and making the best decision for your needs because some stores provide generous return policies.

Where does a Synth Pedal go in my pedalboard?

Using the majority of synth pedals as a guide, it’s ideal to put your pedal as early as possible in the chain, i.e. closer to your preamp pedal. Synths use a mechanism known as ‘tracking,’ which means the pedal can latch on to and detect a note (or range of notes, if you are using a polyphonic unit).

Having a nice, clean signal to work with will considerably improve the circuitry’s tracking ability. As a result, you’ll have more consistency and a better overall sound. If you put the pedal too far up the chain — for example, after a lot of other effects, phaser pedals, and so on — the signal will become congested and won’t track as effectively. This is especially true if it’s used after fuzz or distortion pedals.

However, to each his or her own. There’s nothing wrong with a little trial and error to see what works and what doesn’t. Some players may enjoy the unpredictable nature of a peculiar signal chain arrangement.

Can I use a synth pedal with bass guitar?

Yes, many synth pedals work well with both electric guitar and bass guitar. However, it’s important to check the pedal’s specifications or reviews to ensure it can handle the lower frequency range of a bass.

Do synth pedals work with acoustic guitars?

While most synth pedals are designed for electric guitars, some can also work with acoustic guitars. An acoustic-electric guitar with a built-in pickup is typically needed to provide the electronic signal the synth pedal requires.

Can I use other effects with my synth pedal?

Yes, a synth pedal can be used in combination with other effects. The order of the pedals in your signal chain can have a significant impact on the sound, so it’s worth experimenting to find what works best for your desired tone.

Do I need a special amplifier for a synth pedal?

Typically, no special amplifier is needed for a synth pedal. However, some synth sounds may be better reproduced by a full-range speaker system (like a keyboard or PA amplifier) rather than a traditional guitar amp.

Do synth pedals need a power supply?

Most synth pedals require a power supply, either through a dedicated power adapter or a battery. The specific power requirements can vary between models, so it’s important to check the manufacturer’s specifications.
