G-Lab GSC-3 Guitar System Controller
Guitar System Controller (GSC-3 with metal footswitches and backlighted descriptions) is the programmable switching device of effectsÕ loops (looper), the controller which replaces the ampÕs footswitch and the MIDI foot controller in one. By pressing just a single footswitch it enables:
- To activate selected effects (connected to effects loops)
- To set the amp channel and other ampÕs functions controlled by its footswitch input
- To select program numbers at MIDI devices (e.g. effectsÕ processors) and to transmit Control Change type commands.
True passive signal path doesnÕt contain any active elements (gaining the signal) which could change the guitar tone. All effects and the input buffer are attached by electro-mechanical relays into the signal path (TRUE BYPASSED circuits).
Features:
- six loops for connecting effects
- possibility of switching on the high impedance input buffer (identical with a tube amp characteristics) at any preset
- the TUNER output with the silent tuning function which receives the signal through very high impedance circuit (no influence on a guitar signal)
- six 9V DC outputs supplying effects (in two separated sections, 500mA each)
- 2 separated outputs (2 lines each, latching type) for amp's switching by its footswitch input
- MIDI output for controlling MIDI devices by Program Change and Control Change commands
- tap tempo function (sending the tempo to the MIDI device)
- 100 presets memory (10 banks, 10 presets each)
- possibility of copying of whole bank and single preset
- possibility of putting down the modyficator function to the footswitches (ON/OFF effect, switching amp channel or call the preset on the particular MIDI device
- AUX connector for connecting an extension modules, eg. AUX BANK UP/DOWN FOOTSWITCH WITH MIDI IN
- USB connector for connecting to a PC, enabling downloading, editing and saving presets, also firmware upgrades
- 10 metal footswitches with backlighted descriptions (GSC-3 version)
- 10 silent, backlighted footswitches (GSC-2 version)
- three modes of bank selection and no banks mode
- the input for connecting a wah-wah effect pad (wah-pad) to control the system by placing the foot on the wah-wah effect
- external power supply with 4 meters long and flexible cable
- durable, powder-coated casing.

Great Product, Works as Advertised
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
This product works exactly as described. It makes BM's smoother and gentler. I personally use the unflavored, no sweeteners added version, and honestly, it does not taste very good, but I feel that the results are worth it, and I do not like adding extra sweeteners or flavorings to my diet. I have used this product for many years and have found that about 1 1/2 to 2 tbsps in 12 ounces of water works the best for me. You will need to experiment a bit to find the ratio that works best for you. I recommend that you start on the low side and gradually increase the amount of Metamucil as needed.

Healthy, Effective, and great when mixed with Splenda and Koolaid mix. The best of many options I've tried.
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I've sampled a few different varieties of fiber supplements, including both Benefiber and off-brands, and I found that Metamucil provided the most fiber in the least offensive beverage. Compared to the other brands, this stuff is smoother textured, and goes down easier, as a sort of happy medium between the grittier supplements and the thicker ones.
What about effectiveness? I have apocalyptic IBS, and since starting to take this stuff regularly (one giant glass every morning and evening), my BMs have been much more regular, and more manageable. Flare-ups happen less, and it even seems to do a decent job when taken with meals of cutting the hit to my stomach and gut. I tend to take more than the recommended amount, with an even larger serving of water, as I feel like it helps me stay hydrated and full throughout the day.
I started taking the classic orange Metamucil, but although I really liked the superior flavor (rather like Orange Tang) it packed several times more sugar in each serving than fiber, so while it was great for digestive health, the overall health impact was too negative. I also sampled the sugar-free berry flavors, but found that, although it was ostensibly healthier, the flavor wasn't great, and in addition it suffered from the aspartame aftertaste and further effects (Aspartame gives me headaches). So this was a dilemma for me. What to do? I actually wrote to Metamucil about it, and they recommended this product. The downside is that it comes with absolutely no flavor, so you need to provide your own in order to mask the texture (I wouldn't dream of trying to mix this in plain water--yuck!) The upside is they pack 100+ servings into a container, and you really are free to blend it into whatever suits your fancy. Obviously if you mix it with something like orange juice, then you're already negating the benefits of this stuff over the sugary orange flavor, but I've personally found a much better way.
I like to mix this stuff with Kool-aid mix and Splenda (Sucralose) sweetener. I buy a ton of Splenda and kool-aid as it mixes up tasting sweet, like sugar, but without the calories or aftertaste. You can dump a spoonful of this stuff into a glass of splenda-koolaid, or just dump 8 servings worth of this stuff in with a packet of koolaid powder and a cup of splenda, and then just mix it up and spoon it into water as needed. Better tasting, sugar-free and packed with good useful fiber.
EDIT: I wish I could subscribe to this stuff. Price of splenda has gone up, but I've figured out thatyou can just dump 7 packets of koolaid mix and 7 dashes of sucralose into a container of this and shake it up.

#1 for #2's
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I like the lack of sweeteners and flavor. I just want the stuff that helps me poop. There is some citric acid in it (no idea why) which gives it a mildly acidic taste. Other than that, it does the trick.

Good Stuff
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
If you need more fiber in your diet, you need this. The price is right, it works very well and keeps me regular. I use this instead of the gummies or capsules. That's because you MUST put in in fluid, and hydration is SO important when using a psyllium product as it causes water to be absorbed very quickly once it is ingested, and you don't want to dehydrate! Mixes very well in water and has little to no taste whatsoever. Stay regular, stay hydrated and stay well.

Works well, but is now too expensive...
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
The "No added sweeteners" has been my go-to version of Metamucil, but I'm giving it 4 stars and moving on to another brand as the price is over $35 which is too much imo...
