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.

Really Good Cooling Pillows for Sleeping
Color: Blue-ice Plus, Size: Queen(Pack of 2), Color: Blue-ice Plus, Size: Queen(Pack of 2)
These cooling pillows are very soft and provide excellent support for your head and neck. They are adjustable by taking our the stuffing if you need them to be more flat or less firm. The look great and comes in a pack of two which is a great value. During use, I did notice they have great shape retention and it does not take them long to return to their fluffy full shape. I am a hot sleeper and these do keep your head cool - just be aware using a pillow cover does reduce the cool ability but this allows you to adjust for weather like during winters to add a pillow case for extra warmth. Very happy with this purchase and got a second set to replace my old pillows.

Best pillow ever!
Size: King (2 Pack)
I love this pillow. I like a softer pillow and my partner prefers a firmer pillow. With these pillows you can adjust it to the comfort level you desire. For mine I took out quite a bit of the shredded memory foam (I call it fluff). I took out one 13 gallon trash bag of the fluff. After I slept on my pillow for a couple of weeks I found it was getting to soft so I took my saved bag of fluff and added it into the pillow. Now it's PERFECT! The cooling side works great. When you lay your head down on it you can feel the cool pillow. Helps falling a sleep easier. I would highly recommend this pillow!
