BOSS SY-300 Review – Change the Taste of the Guitar into a Synthesizer

BOSS SY-300 – Before writing any further, I have one question for guitarists: Have we ever imagined playing Rush, “Subdivision” or “Tom Sawyer” songs where we play guitars in every part of the synthesizer? If only it could be played from a guitar it would be something interesting right? For now, we can play it from a real guitar instrument, what’s interesting is that it’s not only real but easy.

Look Ma, This Is NO (Hexaphonic) Pick Up!!

Before the rise of the digital world, the search for a guitar synthesizer was like looking for a very rare treasure. For me personally, mounting a synthesizer on a guitar to produce digital sounds is hardly something that interests me. Technically, there are too many processes that must be followed to produce the sound, such as installing a Midi port and installing a special type of pickup in it.

Now with its polyphonic technology, the BOSS SY-300 changes all that, without the need for a special pick-up, as long as there is an incoming audio signal, the synthesizer sound can be produced by this stompbox without giving any latency. This is because the sound produced is not a sample, but a waveform coming straight from the guitar pick-up, just like conventional effects. Of course, this is a very brilliant revolutionary idea.

BOSS SY-300 Review


Physical Features

This blue stompbox has a 10×7.5-inch media with four control switches, six knobs, seven setting buttons, and an LCD display.

Using a standard inch jack, this device is as simple as a guitar stompbox, which can be directly connected to a guitar amplifier, or to a computer which indirectly makes this tool an audio interface. So we can record directly from the guitar to the computer with this tool. And all processing is digital with a 24-bit, 44.1 kHz converter.

Synth On Board

For the most part, BOSS has achieved success as evidenced by their many products that have become legends in their class. The SY-300 puts a variety of synth sounds into a stompbox format that can be treated just like any other pedal effect, and they do this very well.

You can also strum guitar chords if you need to, and not only can you process them analogously, but you can process more conventional guitar sounds thanks to the well-known built-in BOSS effects. The effects cover almost everything we imagine with overdrive and distortion with a range of mild overdrive sounds to full Fuzz, the same can be said for the Delay, Reverb, Wah, and along the lines of modulation that we can find in other BOSS multi-effects units.

There are 70 presets that can be used if we like to tinker. Of course, we can get 99 unique sound slots assisted by the very easy blender facility, but if we want to take advantage of existing presets we always get a random selection option.

The operation of this effect is very easy, we can set it manually from the existing knob, or directly control it on the LCD screen. In addition, the sound can be directly edited on a computer device by downloading Boss Tone Studio for SY-300 first.

In synth architecture, we can choose several types from separate oscillators, with some predefined settings such as Saw, Triangle, Square, PWM, Detune Saw, etc. Equipped with four effect processors, we can use the original sound of our guitar along with the synth sound or directly merged it into the synth sound.

All of these things can be combined in series or parallel. Very easy to control, edit and use. Interestingly, apart from having three footswitch controls, we still have two special slots for expression pedals.

This will be additional entertainment for guitarists because being able to play synthesizer sounds on the guitar is something that makes guitarists feel at home for a long time exploring guitar sounds, plus the expression pedal where the guitarist has one of the basic characteristics of his liking by stepping on the expression pedal.

I don’t know if this is just my experience or what, when I find the default expression pedal, I want to play expressively and explore more with a reduced level of facial control by 94%, hehe.

For those who like tones or sounds in video games, this is the right tool and can be very helpful in making compositions and recordings easier.

For example, when we play the arpeggios feature, by simply pressing one note on the fretboard, the sound that comes out can be more than five notes in a row with the form of arpeggio and tempo that we can set ourselves. Especially for guitarists who really like strange sounds, of course, this is the right box for you.

Best of all, it’s a powerful tool for creating unusual but useful sounds, and it’s a very powerful partner in the creative process.
