  • If you're on the fence, give it a try, it's a fantastic value!
Style: Guitar/Bass
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! ... show more

  • A great addition to a solo or man band
Style: Guitar/Bass
I have men using EHX “9” series pedals to create Live Loops for my one man band gigs. I thought they were great until I tried this SY-1 to cut down on pedalboard real estate. I have already found some very useable sounds. The bass sounds are great as are the organ and “bell” sounds. I have not yet found a string or pad that works in my set’s but I have only scratched the surface. The one thing this does not do that the Bass 9 does is have a split patch so I can comp and play live bass. That’s a drag sometimes but for making loops in the fly it just means I can’t play bass and shorts simultaneously. For what is does without a divided PU, it’s spectacular. I use this with Nylon String Guitar. ... show more

  • INSTANT GRATIFICATION!
Style: Guitar/Bass
The Boss SY-1 is absolutely fantastic – as long as you like at least some of the 121 presets. Just plug it in and get playing! It takes five seconds to learn how to scroll through the sounds, and maybe two minutes to learn what the parameter dials do. Here’s what you need to know, right out of the box: Effect, the smaller knob on the left, is the volume for the synth signal – turn it down if the synth effect is too loud. Direct, the larger knob on the left, is the volume for the source signal (your guitar, or whatever). Use these two together as your mixer. Most of these sounds are too 80’s synth-y for me, and there are some in the SFX and SEQ sets that I wouldn’t touch with a ten-foot pole. That’s perfectly OK though, because there are at least twenty voices that I really like – Bell 7, plus reverb and chorus from my pedalboard, is my favorite voice for chords. There’s really nothing to dislike about the SY-1 (unless you dislike the sounds). What it doesn’t do – and why I’ll probably upgrade to the SY-200 – is save your settings. Switching sounds means changing parameters, most of the time. For the price though, you won’t do any better. It’s a Boss, which means as long as you don’t drive over it with a truck or drop it from the Eiffel Tower, it’ll last forever. Update: I upgraded to the SY-200, and whoa Nelly it's worth the extra hundred bucks. Fifty more voices, including decent rotary organ voices (better than the SY-1), and the ability to save your presets. ... show more

  • Fun pedal to have on the board.
Style: Guitar/Bass
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. ... show more
