With a legacy spanning almost half a century, Boss and Roland have consistently led the forefront of guitar synthesizer innovation. The Boss GM-800 Guitar Synthesizer stands as a testament to this, providing guitarists and bassists with access to an unprecedented array of creative tools. Harnessing the formidable ZEN-Core sound engine and the newly designed Serial GK interface, the GM-800 represents a significant step forward in guitar synthesis.

The heart of the GM-800 lies in its ZEN-Core Synthesis System. Adopted from Roland's flagship synthesizers, the ZEN-Core engine is capable of producing over 1200 different tones. Spanning from classic acoustic sounds to the iconic Roland synths like the JUPITER-8 and JUNO-106, this library of tones presents an expansive playground for your musical imagination. Moreover, this sound palette is extendable through Roland Cloud, giving you access to a continuous stream of creative content.

Each scene on the GM-800 is a "super patch" that allows you to combine, layer, and edit four unique Tones, plus Rhythm. With the high-performance DSP, you can seamlessly transition from one scene to another, ensuring smooth performance. Moreover, with 150 user-configurable scenes, including 100 that come preloaded with professional ready-to-play sounds, you can customize your sonic environment to match your creative vision.

On the effects front, the GM-800 is packed with over 90 effect types, with each scene capable of supporting multiple effect applications. From distortions and modulations to delays and more, the effects on offer ensure that your sounds are uniquely yours.

As a performance tool, the GM-800 lets you go beyond the traditional guitar and bass sounds. With continuous pitch control, chromatic operation, and advanced pitch detection, the GM-800 can transform your guitar or bass into a multifaceted sonic device. It can also function as a standalone synthesizer sound module for MIDI keyboard use or DAW sound expansion.

The GM-800 also houses two external control jacks for up to two footswitches or an expression pedal, giving you greater control over your performance. It integrates seamlessly with your desktop or pedalboard setup and also features MIDI I/O for interfacing with a wide range of MIDI equipment.

With USB audio/MIDI connectivity and guitar to MIDI function, the GM-800 extends its functionality even further. It can serve as a compact, portable MIDI sound module, a premium sound source in your DAW, or can be used to play external MIDI instruments via USB or a MIDI cable.

Rounding up, the GM-800 comes with BOSS Tone Studio software that lets you craft and organize your sounds from your computer. With all these features and more, the Boss GM-800 Guitar Synthesizer is more than a pedal—it's a world of unlimited musical possibilities.

Good quality pillows overall
Size: King (Pack of 2), Color: White
Got a set of these for my wife and myself as we were struggling with our old pillows. These have some really good qualities and some things we'd like to see changed. First, the good: These are look and feel like they are high quality and made with good materials. The foam itself has a very nice feel to it. We love the fact they are adjustable to add or remove foam. They come with a pretty substantial amount already in the pillow. We appreciate the CertiPur certification. Now the improvements or changes we'd like to see: The foam, while feeling great, doesn't bounce back well if you scrunch your pillows, and so every day you have to fluff and reshape the pillow, moreso than some other memory foam pillows we've owned. One side of the pillow is cooled and you can feel that even through the pillow case, and that's a great thing. However, one side is not cooled and we'd have preferred if both sides were made of the cooling material. Overall, these are good pillows and we are not disappointed with the purchase. They are not, however, our perfect pillows (which do seem hard to find), and at some point in the future will probably make their way to the guest bedroom. We would rate them as some of the better pillows we've tried and feel most people would probably like them.

Perfect Pillow
Size: Queen (Pack of 1), Color: White
These are the best pillows ever. You can adjust the firmness or softness to whatever you want. For years i used a soft latex pillow , which you cant get anymore. I will never use another pillow. I have purchased 6 of these after the first one. You pick your own comfort level. Best ever. No more neck aches.

Hallelujah… finally, I found the right pillow!!!
Size: Queen (Pack of 1), Color: White
I have spent a lot of money searching for the right pillow. I recently tried to Tempur-pedic that cost twice with this pillow cost. Tempur-pedic flattened out. I’ve had this pill for a few weeks now and it works wonders. I am a paraplegic. You can have a lot of neck problems. I love the fact that this pillow is adjustable. I immediately saw it was too stuffy and took a bunch out. It works perfect so glad I didn’t spend money on a $200 purple pillow. I read a lot of reviews and there were a lot of complaints about the odor. Mine did smell funny when it came out of the box. I immediately threw it in the dryer with a few bounce fabric sheets came out smelling fine. Pillows are a very individual thing, but I think for 40 bucks this pillow is worth a try. I’m really enjoying mine about one of those silk pillowcases to go over it and it sleeps cool and comfortable. Best wishes in your search for the right pillow. Update: I’ve been using this pillow several months and it continues. Give me a good night rest pain-free.. well worth the money. UPDATE: I have been using this pillow for three months and it still works great. It does not flat out or get hot..

Soft comfortable very good pillow
Size: King (Pack of 1), Color: White
I really love my new pillow it's great and comfortable. Yes, it has a little smell, but if you wash the pillowcase and put the pillow on the window for a day you won't notice anything anymore.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend
