Beetronics Swarm Analog Fuzz Harmonizer PedalThe Swarm is an Analog Fuzz Harmonizer that sounds like a thousand killer bees coming to get you!
It basically turns your input signal into a square wave, than multiplies and divides the frequency of that wave, giving you nine possible harmonies in two different octaves. Modulation is applied to the harmonies making them go from a nearly perfect tracking harmony, to a wild and uncontrollable swarm of mad bees.
The WORKER sets the level of your input signal, now fuzzy and buzzy. The SPECIES allows you to select between 9 different intervals for your harmonies. The QUEEN and DRONE set the levels for each of the harmonies that stay one octave apart.
The FLIGHT and STING control the modulation applied to the harmonies. They are highly interactive controls and you will find many different sounds by just messing with these. STING sets how fast or slow the harmonies will follow your playing. Turn it CCW for it to feel like the harmonies sting you at every note you play. Turn it CW and the harmonies will sound like a drunk bee hovering up and down around the root. FLIGHT will set the response of the modulation. CCW the harmonies will keep it oscillating up and down, while CW it will glide and hold from one note to the next.
The MASTER control will set your output volume.
With all that said, no matter how one tries to explain the theory and what each control does, the Swarm is best when played by instinct. Mess with every control until you find a tone that you like and let the bees take you to sonic places you've never been!

AMAZING - LOVE THESE!
Color: Blue, Size: Queen (U.S. Standard), Set name: Stretchy and Soft
I've been using these pillow cases for more than 6 months and LOVE them. They are well made, no wrinkling, fraying or wearing out, even with a weekly washing. I love the zippers on them, my pillows fits perfectly in the case and don't constantly escape from the case overnight. They definitely perform as described: they keep me cool at night and don't smell and actually don't make a mess of my hair. I bought an extra one and put it on a pillow I keep close to my body which helps me from overheating during the night. They are a great value for the price, I wish I could get top sheets in the same style as these and I'd be in heaven!

Cool Pillowcases
Color: Gray, Size: Queen (U.S. Standard), Set name: Stretchy and Soft
These pillow cases are silky soft and cool to the touch. They don’t stay as cool as I would like, however, so I find myself moving around on the pillow to find a cool spot or flipping the pillow over. I have washed them several times and the coolness seems to be diminishing. Still, it’s better than a regular cotton pillow case. The zipper is needed and helps keep the material on the pillow.

Great pillow, but the cooling effect depends on the cover
Color: Blue-ice Plus, Size: King(Pack of 2)
I really like this pillow overall. It’s comfortable, supportive, and feels well made. When you use it without a pillowcase, it definitely feels cool to the touch and does what it claims in terms of that initial cooling sensation.
However, once you put a pillowcase on it, you can’t really feel the cooling effect anymore. I’ve tried multiple different pillowcases made from different materials, and none of them really let that cool feeling come through.
That said, I still love the pillow itself. It’s comfortable and supportive enough that I’m keeping it. Just keep in mind that the cooling feature works best without a cover, which isn’t ideal for everyone.
Overall, a good pillow — just manage expectations about the cooling effect once it’s covered.
