The Surfy Industries - StereoMaker is fully buffered, transformer isolated, ABY switcher containing pseudo-stereo effects. Complementary analog comb filtering makes it possible to simulate the mixture of direct and reflected sound waves in a room in a very realistic way. 180 degrees phase reverse and ground lift helps cleanup any hollow sounds that can occur using two amps. A great, new, highly usable utility pedal from Surfy Industries.

From Surfy Industries:

An ABY pedal typically receives the signal from a guitar or other instrument and splits it into two outputs. The StereoMaker is fully buffered and packed with features like: soft touch JFET switching, transformer isolated outputs, pseudo stereo effects, 180 degrees phase reverse and ground lift.

In STEREO mode the width and volume controls are enabled to optimize a pseudo stereo sound. The PAD switch makes it possible to attenuate line level signal to instrument level. Also the StereoMaker can be used as a direct box to convert unbalanced to balanced signals becoming a usefultool for keyboard players and recording studios.

PSEUDO STEREO EFFECT (Y)
A simulated stereo effect is generated using analog complementary comb filters. This unique implementation makes it possible to simulate the mixture of direct and reflected sound waves in a room in a very realistic way. This effect is 100% analog and safe to mix back into mono, no side effects.

OUT-OF-PHASE SIGNALS
Sometimes reverse phase effects can occur resulting in a "non-distinct", "hollow sound". The reason might be that two guitar amps has been used with different number of gain stages. The StereoMaker has a built-in 180 degrees polarity reverse circuit to phase-match amps. Just pull the output plug half way out to get the reverse phase.

This is a nice mat for floor exercises.
Color: Aqua, Style: 1-Inch
I had some lower back issues and went to physical therapy. I used this mat for my floor stretches and exercises at home along with my big rubber ball. It made the floor work so much more comfortable. Beware of the smell. When I unroll it I still smell that “memory foam” odor, which takes some getting used to. I aired it out as instructed, twice, and it persists. It’s a wonderful mat so the odor is not a deal breaker. I’d buy it again.

Maximum joint comfort and durability
Color: Pink, Style: 1/2 Inch
I absolutely loved the color, and it offers incredible cushioning without sacrificing stability during balance poses. It is dense, doesn't lose its shape, and springs back instantly. The materials are high-quality, and it doesn't have that strong plastic smell that others often have. It is worth every penny for the comfort it provides.

These sunglasses are such a great combination of style, comfort, and value.

I absolutely love these sunglasses. They’re lightweight, comfortable, and fit perfectly without constantly sliding down your face. The medium-sized frame is super flattering and works well for both workouts and everyday wear, which honestly makes them one of the most versatile pairs I own. The polarized lenses do a great job cutting glare, especially for driving, beach days, walks, and outdoor activities, and I appreciate that they still feel stylish instead of overly sporty. The quality is impressive for the price point, and they’re durable enough that I don’t panic about bringing them on trips, hikes, boat days, or throwing them in my bag. They’ve definitely become my go-to sunglasses for everything from walking the dog to vacations to casual everyday errands. Cute, functional, affordable, and surprisingly high quality.

Impressed! Perfect for summer
Color: Phoenix at a Bloody Mary Bar V3
These sunglasses are spectacular, i am very impressed for the price point. Affordable, good quality, lightweight, and fit perfectly! I have very sensitive eyes, so I have to be very picky about the sunglasses I wear, usually having to spend $$ for a good pair. These pass the test, at a fraction of the cost. The lenses are polarized and block the sun fairly well. Wore these on a walk as soon as I bought them, and I am already wanting to buy another pair!! definitely recommend, if you are looking for something that is sleek, but fun. Can also be a great gift!! Love the variety of color options!

Great quality, durable, and stylish
Goodr are some of the best sunglasses you can buy at this price point, whether you’re an athlete or just want them for casual use. I love the matte black finish, which is just a touch lighter than my own soul :). The polarization and general glare reduction have been great on extra sunny days. I recently dropped them from my head on concrete or asphalt, and even though a lens popped out, I was able to get it back in place with quite a bit of effort - which is good, because I’m still confident it won’t pop out easily. There was only some minor scratching on the frame that mostly wiped off but it held up just fine, so +1 for durability!
