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.

Very comfy sheets, nice fabric
Size: Full, Color: Oatmeal
I wasn’t expecting such good quality forthis price. They’re very soft, but of fairly thick fabric. I’m sleeping great on them. The pockets are deep enough for an 8” foam mattress plus my 3” topper. Will be getting another set for the second bedroom.

Great Sheets!
Size: Twin, Color: Oatmeal
Super soft, wash up beautifully, seem well made — very happy! It’s very hard to find 100% cotton t-shirt type sheets and these are really lovely.

Weirdly textured
Size: King, Color: Dark Gray
I have bought and loved jersey sheets in the past, that have all been as soft as a well worn cotton t-shirt. These arent soft. They have the stretch of jersey, but not the soft smooth texture that they should have. Even after washing a few times these are one of my least favorite sheets I've ever bought on Amazon.

My second pair! ❤️
Color: Brown, Lens Width: 37 Millimeters, Color: Brown, Lens Width: 37 Millimeters
If I could give these glasses ten stars, I would! In fact I just ordered a second pair. I’ve been an Amazon customer for years and this is by far the best deal I’ve ever had. These are legit, well made Harley Davidson sunglasses with the Harley tag attached. They are worth WAY more than the $13 that I paid. They came in a hard shell Harley Davidson case! Last year I bought the same case for my husband’s glasses and the case alone was $14.99! Don’t hesitate to buy these! I was concerned about the size but figured I could return them. The size is perfect and comparable to glasses you’d find anywhere.
