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.

Most cost effective product
Size: 1.5 Fl Oz (Pack of 2)
I have an issue with my mouth going dry due to CPAP use. This spray is better priced than other sprays but, not quite as refreshing. Due to the cost savings, I will continue to order this product.

Awful taste
Size: 1.5 Fl Oz (Pack of 2)
It tastes terrible, and after trying to get used to it, it didn't work. I have used it three times a day and I still have no benefit from it. It feels very dry at night and aggravated my dry mouth when I woke up. I also purchased the toothpaste and the mouthwash to go with it and it was a total waste of money.

Must Read Book To Improve Health and Aging
Format: Hardcover, Format: Hardcover
Jessie Inchauspe is brilliant. This book is full of very useful and effective information building on her 10 Hacks found on her YouTube videos. As a biochemist and medical researcher, she is considerably more knowledgeable than many physicians I've met about nutrition and its impact on health. I have been struggling with borderline diabetes/pre-diabetes for years. Doctors wanted to put me on Metformin which I refused as I’m improving and reversing this condition through diet, exercise, and natural supplements. This is a very interesting easy to read book that fully explains how important it is to balance and flatten glucose spikes and improve insulin sensitivity. Many people know ”What” to eat and what foods to avoid, intermittent fasting addresses “When” to eat. This book discusses “How" to eat in a particular order to noticeably benefit health. She explains glucose spikes and insulin resistance and its relationship impacting health, chronic illnesses and aging. She states that chronic diseases including heart, cancer, obesity, diabetes, dementia, PCOS, and others are from inflammation stemming from uncontrolled glucose spikes. Feeding children in this particular order can also improve their health- childhood diabetes is a major concern. Inchauspe cites a 2015 Cornell Study which found that people who ate food in this order (described below) reduced glucose spikes by 73% and insulin spikes by 48% within 2 hours, along with a significant reduction in their A1C levels. This is huge! My own blood testing and eating a variety of foods in this order, including various desserts, shows an impressive further reduction in my 2 hour postprandial blood glucose readings which are typically in the 90's or very low hundreds. The 10 Hacks found in her YouTube videos are greatly expanded upon in this book to make these hacks even more effective in normalizing glucose and improving blood testing and A1C scores, while helping to lose weight by eating foods in a certain order: First- salads and/or veggies. Second- protein and good fats. Third and last- carbohydrates & starches. Yes, you can eat whatever you want, and however much you want (no counting calories) and even have dessert as part of the meal while minimizing glucose spikes and fat storage, improving insulin sensitivity and overall health. If you need to lose weight or have blood glucose challenges, skip dessert and reduce or eliminate bad carbs and limit good carbs. Eating in this order becomes a lifestyle and easy to implement daily. I find eating this way that I’m already pretty full by the time I get to the carb and dessert stage which helps maintain my weight. Other hacks include drinking a tablespoon of apple cider vinegar in water or in a dressing, not eating naked carbs (take carbs with a good fat or protein), and walking after a meal or doing slow calf raising exercises while seated at the table. I have been doing intermittent fasting for over 6 years and it has been a major driver in my own improvement in reducing A1C scores. I get my blood tested every 4 months. I vary fasting between OMAD ( 1 meal a day), 20:4, 22:2, 19:5, 18:6, and 16:8 depending on schedule eating no more than 2 meals a day and no snacking. Fasting reduces inflammation which is a main driver of diabetes. I’m doing a modified keto diet mainly with healthy whole food items. Combining fasting wth eating food in the proper order is effective in reducing glucose and easy to implement. Doing calf raises while seated which target the Soleus muscle in the calves is very powerful. The Soleus muscle is the only muscle in the body which absorbs glucose from the bloodstream. I try to do calf raises while sitting at the dining table at the end of a meal for at least 10 minutes. This can reduce glucose spikes by 52 percent and insulin by 60 percent. Google the ‘Soleus muscle glucose metabolism’ for more info. I also do a few simple Tai Chi exercises I found on YouTube. I have also been taking Dihydro Berberine which is more effective than regular Berberine. I use Heal Meal brand. My functional health MD upped dosage to 5 a day- 3 at first meal, 2 at my second and last meal- which has reduced my glucose spikes in a major way versus 4 daily. Take 20 minutes before eating. Highly recommended! Update September 2024- I recently got a Dexcom G7 continuous glucose monitor (CGM) which has been very educational in seeing how good quality sleep and walking after meals helps to further lower glucose levels, versus poor sleep and no walking after eating. Drinking a 1-2 tablespoons of apple cider vinegar in a glass of water before a meal, especially a high carb meal, is very powerful in reducing glucose spikes. I used to get up at 3am to go on the computer every morning. Forcing myself to break this habit and stay in bed has seen a further lowering of blood glucose after several days. A good night’s sleep and exercise after eating are as essential as diet. This is clearly shown on the CGM which reports glucose changes every 5 minutes. Seeing how various foods impact glucose is a valuable learning tool. I had to pay for this out of pocket and it has been a worthwhile investment. When installing a new monitor every 10 days I find it necessary to recalibrate the Dexcom readings with a fingertip blood test, as the initial readings were too high, typically anywhere from 10-35 points higher than the blood test. Simply click on the plus sign and follow directions to recalibrate.
