Take your guitar into the world of sound creation with the SY-300 Guitar Synthesizer from BOSS. No special pickup required. Just plug your guitars right into the 1/4-inch jack and play! Brand new BOSS technology gets you fat, analog-style polyphonic synth sounds with zero latency, seamlessly extending the natural expressiveness and familiar feel of your favorite guitar. You can also shape your actual guitar tone with the onboard filters, amps, and LFOs. From soundscapes, to leads, to textural pads, and everything in between, the SY-300 lets you create sounds never heard before.An analog-style synth for guitar

The BOSS SY-300's powerful polyphonic synth engine brings a limitless range of new sounds to your arsenal. Just like with the classic analog synths of the world, you have complete creative freedom to invent sounds with a full palette of synthesis parameters. Select different wave shapes, tweak them with filter, amp, and pitch controls. Or modulate them with LFOs, and layer oscillators for rich, complex tones. Dig into the Blender function to mix and match settings from different synth patches to open whole new possibilities of sounds.

Amazing sounds accessed by your guitar's standard 1/4" jack

Tapping into BOSS's legendary guitar synth technology has never been easier. Most guitar based synth products require a special pickup, cable, or even guitar design to access different sounds. But the SY-300 can be used with any guitar's standard 1/4" cable. And ultra-fast DSP, along with newly developed innovations from the BOSS engineering team lets the SY-300 perform absolutely latency free! Now you can get new palette of sounds, that are a natural extension of your guitar playing. You are free to connect with your guitar just as you always have.

Beyond its amazing synth voices, the SY-300's synth engine can be used to process your normal guitar sound as well. Apply filtering to alter the basic tonality, use amp parameters to alter your attack and decay. Even add some movement with the LFO and step sequencer to create complex rhythmic tonalities.

This sunscreen is well-known, but let me tell you about the manufacturer….
Size: 7 Fl Oz (Pack of 1), Style: SPF 30
Have been using this sunscreen for most of my life—it’s been around forever. Product consistency has always been 100 percent perfect. But a few weeks ago I purchased the sunscreen I’m reviewing here, and when I went to use it, rather than finding a well-blended white lotion, the lotion had separated into white clumps and a watery liquid. The product was clearly defective even though it was well within its use-by date. I reached out to Coppertone via email and asked for a product replacement. They got back to me that same afternoon with a letter of apology, sent me coupons for a few free bottles of this sunscreen, included some additional discount coupons for Coppertone products, and also sent a prepaid label and pouch to return the defective product since they wanted to make sure that they were able to solve whatever had led to that product being released in that condition. All in all, I was impressed. Coppertone is clearly a firm with a customer-centric culture, and a commitment to product quality. I thought I’d share this since it isn’t everyday that customers gets an inside look into the culture and values of an otherwise very well-known, market leading firm like Coppertone.

Perfect Travel Size TSA approved size
Size: 3 Fl Oz (Pack of 2), Style: SPF 50
I recently bought the Coppertone SPORT Sunscreen SPF 50 Lotion in travel size for my son’s first trip to Cancun alone, and I have to say, it was a fantastic choice! Whether you're headed to a sunny beach, a day of fishing, or just need reliable protection from the sun, this sunscreen delivers. Here’s my review based on its performance during the trip: Convenience and Travel-Friendly: The travel size is perfect for anyone on the go. It’s small enough to meet TSA guidelines for carry-ons, so you don’t have to worry about checking luggage or dealing with oversized bottles at security. My son was able to easily pack it in his carry-on without any hassle. Additionally, the compact size makes it super convenient to throw into a pocket or backpack for a day of fishing, beach trips, or any outdoor adventure. Sun Protection: The SPF 50 provides excellent protection from harmful UVA and UVB rays, which is especially important for long hours spent in the sun. Cancun’s sun can be intense, and my son was out in the elements for several hours each day (and I wasn't there to remind him to reapply sunscreen), whether he was fishing, swimming, or just relaxing at the beach. He didn’t get burned once!! As a mother of a redheaded 18 year old son I've spent the past 18 years of my life ensuring he wasn't scorched by the sun and Coppertone has yet to let us down! Water Resistance: The water-resistant formula is a huge plus, especially in places like Cancun, where you’ll likely be in and out of the water. My son spent plenty of time swimming and snorkeling, and the sunscreen stayed put. It lasted through sweating, splashing, and even sea water exposure without needing constant reapplication. It’s perfect for active outdoor activities, whether you're swimming, surfing, or just sweating it out in the sun. Mother approved!!

Dries clear, moisturizing, silky, great value
Size: 5 Fl Oz (Pack of 1), Style: SPF 50
I have fair to light combination skin. I use this on my body, but not my face. It goes on very thick and white, but sinks into the skin lightning fast (within just a few seconds), and it becomes completely invisible. It leaves my skin moisturized and looking and feeling silky. Best body sunscreen I've ever tried. And I love that it is water resistant! I find it too heavy and moisturizing to use on my face, but people with dry skin would probably love it for the face, too. I imagine it would be fantastic for them under makeup. The price per ounce is very reasonable, making it a great value.

Reliable Sun Protection for Active Days!
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Coppertone SPORT SPF 50 is my go-to sunscreen for outdoor activities. It’s lightweight, non-greasy, and stays on even when I’m sweating or swimming. The broad-spectrum formula protects against both UVA and UVB rays, giving me peace of mind during long hours in the sun. The 3 fl oz size is perfect for carrying in a gym bag, backpack, or beach tote, making it easy to reapply throughout the day. It absorbs quickly and doesn’t leave a sticky residue, which is great for sports or active adventures. Highly recommend for anyone who wants effective, durable sun protection without sacrificing comfort or mobility!

IT does protect from the sun.
Size: 5 Fl Oz (Pack of 1), Style: SPF 50
It protects from the sun without a doubt and lasts well. The downsides are that it leaves a greasy and "white" residue that no matter how much you rub it in.....it stays there. I use it when I am working outside and not planning on going anywhere anytime soon.
