The Boss SY-300 unlocks synth power for guitarists without the need for special pickups or cables. Plug in any standard 1/4-inch instrument and access a zero-latency polyphonic synth engine designed to track your playing with total accuracy. Three fully independent oscillators power the core of the sound design system, each offering a range of selectable waveforms including sine, triangle, saw, square, pulse-width modulation, detuned saw, noise, and even an input waveform to blend your dry tone directly into the synth structure.

Each oscillator can be shaped with standard analog-style parameters—filter cutoff and resonance, amplitude envelope, and pitch tuning—as well as LFO modulation, making complex layered patches easily attainable. Add movement and articulation via the step sequencer or use the Blender function to fuse parameters from different presets into new creations on the fly. Whether designing pads, leads, rhythmic pulses, or chaotic textures, the synth engine responds dynamically to your playing without compromising technique or timing.

Four simultaneous effect blocks provide expansive tone-shaping control with over 20 selectable types. Options include classics like phaser, flanger, and tremolo, along with layered effect combinations such as chorus plus delay, or delay plus reverb. More experimental entries like slicer, lo-fi, isolator, and slow gear push the SY-300 beyond traditional pedalboard boundaries. Each effect engine can process synth voices, dry guitar, or both, allowing full customization of routing and tone.

Additional performance tools include assignable footswitches, external control via MIDI or expression pedals, stereo I/O with dry signal pass-through, and a USB interface for audio recording, patch editing, and patch sharing through Boss Tone Studio. The SY-300 is a multi-layered creative platform engineered for exploration.

Extremely poor quality. Too flexible!
Size: 1000 Teaspoons
Poor quality, flimsy, barely strong enough to stir my coffee. Not strong enough to use for eating even semi-solid food. Too much flex!

Great Quality for the Price
Size: 100 Count (Pack of 1)
Love these paper plates. They’re sturdy, microwave-safe, and hold up well without getting soggy or folding easily. Great for everyday use and cleanup is super convenient. Good value for the price and reliable for meals and snacks.

Nice and sturdy!
Size: 300 Count
This was our first time to try the Amazon Basics Everyday Plates. I typically purchase paper plates in bulk from a big box club store. These are just as good, if not better! They are thick and sturdy, and hold up well. The price point it also better! My only negative is the design on the plate isn’t the most appealing. I think it’d be better if the design was limited to just being on the edge, and not across the entire plate.

Great Size, Strong Enough for Everyday Use, and Worth Reordering
Size: 300 Count
I reorder these regularly, and that really says the most. They’ve been consistent, practical, and a good value for what you get. They’re strong enough to handle normal meals without feeling like they’re going to give way. I’ve had no issues using them for everyday food, and they hold up well as long as you’re using them as intended. I also like the size. They’re a little over 8½ inches, which works well for most meals. If I have something heavier, I can put a plate holder underneath, and these still fit just fine. The print/design is simple, which I don’t mind at all. I’m more concerned with how they perform, and these do what I need them to do. I’ve used name-brand paper plates before, and for my everyday use, I feel like these compare very well, especially considering the price. I’ll also be honest—paper plates just make sense for me. I tend to drop things because of how my hands work, so this helps prevent broken dishes and the cleanup that comes with that. Plus, it definitely cuts down on doing dishes. Overall, these are reliable, affordable, and something I’ll continue to reorder.
