## Description

With the SY-1, it’s never been easier to infuse your creative arsenal with BOSS’s legendary guitar synth technology. This amazingly expressive tool is filled with 121 ultra-responsive sounds, all distilled down into a BOSS compact pedal that slides easily into any setup. Best of all, it’s as simple to use as a standard stompbox, so you don’t need any background in synth programming to bring a new world of sonic textures to your music.

Review: Fun pedal to have on the board. - It has a couple effects that I probably won’t use much, but it’s a great pedal on my board. I have my SY-1 feeding into the Boss SL-2 Slicer feeding into a Boss PS-6 Harmonist into a Boss DD-8 Digital Delay into the Boss RV-6 Reverb. The sound is magical with tons of room for creating your own unique sounds. Since the pedals I listed above are all modulation pedals, they will sound best through the effects loop on your amplifier (if it is so equipped). The SY-1 also pairs well with other instruments, my violin sounds great through it and so does my Les Paul using a violin bow to play it. Keyboards sound great, ukulele’s, mandolins and bass guitar are all instruments the SY-1 can substantially enhance. In summary, fun pedal, built to Boss’s standards that can enhance your church playing or send you to freakyville. Very versatile pedal, highly recommended.
Review: Awesome pedal. - I bought this because my band doesn't have a keyboard player and there are key spots in some songs where some soft orchestra music would be very beneficial. This fits the bill beautifully. By adding an expression pedal I'm able to fade the effect in and out as needed. The sounds are very authentic and high quality. Realistically it only has about three sounds that I'll for the kind of music that I do, but I feel confident that there's something in there for everyone. I used it at our last jam session and it was the star of the show. At least one of the people who heard has ordered one and I'm sure there will be more. I'm very happy with this purchase.

## Questions & Answers

**Q: Is this pedal for Bass, and Guitar?**
A: This pedal can be used with guitar and bass.

**Q: can you play chords with this?**
A: Yes. Many of the settings are already harmonized, too. This is a Guitar Synth that I've seen a bass player on video play through as well. To get the full use of this pedal, purchase the expression pedal. That'll give you the nice filter sweeps on chords & single notes.

**Q: Is there a power supply?**
A: Comes with a battery I bought a boss pedal board with a power supply

**Q: Does this produce a stereo output?**
A: No. There is only on output and splitting it does not create stereo output.

### ⭐⭐⭐⭐⭐ If you're on the fence, give it a try, it's a fantastic value!
*by C***S on April 23, 2024*

I can play keys okayish, but I'm mainly a guitarist and bassist. I use synth and guitar on a lot of the music I do, and I've always wanted a simple solution to switch between synth tones and guitar. I've tried several types guitar synths, and none of them have had a good combination of versatility, tone, and easy of use. This pedal does close everything I'd need it to and it's small and compact. Sure, some of the sounds are more convincing/all around better than others, but in the mix, it barely matters. Additionally, the ability to use it inline with other effects so easily smooths over a lot of the minor deficiencies you might find. Also, I'd say it's better for bass than guitar, but great for both. You can get some great classic synth bass sounds out it with relative ease. The worst thing about it is it has so many sounds and so much versatility that you might need to develop some way to mark down what you're doing to get the tones and sounds you like the most! Definite give it a shot, especially if you're a bassist in a band that needs some occasional synth bass sounds!
