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:

Perfect Summer Tank!
Size: X-Large, Color: Black
I recently added the Amazon Essentials Relaxed Fit Sleeveless T-Shirt to my everyday wardrobe, and I’ve been pleasantly surprised by how versatile and comfortable it is.
Fit & Comfort:
True to its name, the relaxed fit is roomy without looking baggy. It’s ideal for casual wear, working out, or layering under jackets and cardigans. The sleeveless cut offers great freedom of movement, and the armholes are well-designed—not too tight and not too loose. It’s flattering on different body types and long enough to cover the waistband comfortably.
Fabric Quality:
The cotton blend is soft, breathable, and holds up well in the wash. It’s not too thin or see-through, which I appreciate. It also doesn’t cling, making it perfect for hot days or light workouts.
Style & Versatility:
The design is simple but stylish—easy to pair with leggings, shorts, or jeans. Available in multiple colors, so it’s easy to stock up for mix-and-match options.
Price Point:
Great value for the price. It's budget-friendly without feeling cheap, and it performs just as well as more expensive basics from other brands.
Minor Cons:
Some lighter colors may show sweat slightly more.
If you prefer a more fitted look, you may want to size down.
Final Verdict:
The Amazon Essentials Relaxed Fit Sleeveless T-Shirt is a solid everyday staple—comfortable, affordable, and stylish in a low-key way. Whether you're lounging, running errands, or hitting the gym, this tee gets the job done.

Great Top for a Great Price
Size: Large, Color: Plum, Size: Large, Color: Plum
This is a very comfortable tank top. The fabric is lightweight and very soft. I also like the length and the fact that the armholes are not too big. In the pictures added you can see a side view. I was wearing a compression style workout bra that comes up higher, so it works perfectly when working out around others (maintains some sense of modesty). For reference, I am 5'7" and 145lbs and I ordered a large. I love the color and the feel of the top. It is very comfortable for work outs or just lounging.

Sheer and Soft.
Size: Medium, Color: White
This shirt was purchased to be worn for tennis during our hot, August days in Texas. It is very lightweight and exceptionally soft. The cut is flattering - especially the armholes, which are at the perfect place - not too low so that your bra shows, and not too high to impede movement. The color is "white," but it is more of a light cream color. I did not give it five stars because it came out of a gentle washing and light drying very wrinkled, which was a big disappointment. I was hoping for Wash & Wear, but I had to steam it to get out the wrinkles. Also - it's almost too sheer ... I will probably wear a colored bra underneath it with a matching colored tennis skirt to look purposefully coordinated. While I am not familiar with yoga, Pilates, or gym attire, I would imagine that this shirt would be perfect for these types of exercise. I ordered the Medium (instead of the Large, which was suggested for me by Amazon). The Medium fit is perfect - it falls gracefully and is not tight anywhere - the large would have been too big.
