Long a studio trick of the trade, sample rate reduction (commonly called bitcrushing" though the two are different) is a relatively new effect that takes snapshots of your input signal and "approximates" them with less and less accuracy as the effect intensifies. While virtually unknown to most just a decade ago, many modern synthesizers and outboard processing devices now come equipped with this effect. In a nutshell, it makes your guitar or other instrument sound like old-school video games. We've leveled up this effect by offering one simple addition: the humble Mix control. With this, you can use our Bitcrusher kit to destroy your signal as much or as little as you want with a simple twist. You can use the Bitcrusher as a processor for your other effects, blending in just a little for some amazing unique textures, or a ton for complete annihilation. In the epoch of guitar effects, "bitcrushing" and "sample rate reduction" are among the newest. Despite its funky and rare usage, even ring modulators were available in the '60s. However, bitcrushing and sample rate reduction are distinct byproducts of digital technology, more specifically they pertain to quantization errors with respect to different axes. Be that as it may, the two terms have been conflated for years, but neither of these names appeared organically in the first iterations of these effects. The DigiTech Space Station called their sample rate reduction program "Pixelator". Another early example-the Alesis Bitrman-calls theirs "Decimator". Even though bitcrushing involves lowering the bit depth of the signal, it is the sample rate reducer that evokes the sounds most associated with '80s video games, and so that term became entangled with the concept of bitcrushing, such that many gearheads use the terms interchangeably and call it a day. It's like in Texas, "Coke" at a restaurant can mean any type of soda. I disagree with both of these but the public has won out. So, what does all this actually sound like? Well, sample rate reduction takes "snapshots" of the input signal at some high rate, and then drops the frequency at which these snapshots are taken into the audible range such that we can hear them. Each of these snapshots (Riemann sums for you math folks) becomes wider as sample rate is reduced, forming a "stepped approximation" of the input signal. The lower the sample frequency, the more "pixelated" with waveform looks, which is likely why DigiTech chose the program name in the Space Station. Either way, it reminds me of Atari games. Our Bitcrusher kit is taken from the engine of one of our old-school pedals, the Heliotrope, which was itself an adaptation of an old DIY project, called (fittingly) "analog bit crusher." If any effect begs for a mix control, it's this. And surprisingly, many pedals that do this do not offer one. We do, and it makes for an absolutely killer effect. Run other pedals into it for some otherworldly flavor you just can't find anywhere else. Controls - Degrade: This knob governs the sample rate. Fully down, the sample rate is not in the audio range, and so no effect is heard. Nudging the control up introduces some digital aliasing. Depending on where the knob is set, the "snapshots" are small enough to cause "note errors", do not try to tune your guitar with this on. When maxed out, the signal is completely destroyed, like getting blown to bits in Asteroids. NOTE: The original setup for both the DIY schematic and our Heliotrope features a slight "whine noise" in the background. For this kit, many steps were taken to mitigate this noise and it is certainly lower in volume than the originals. Nevertheless, it is still there, albeit quiet. - Mix: Controls a full wet-dry blend between the input signal and the effect. When the knob is fully down, only the dry signal is heard. When it is fully up, only the effect is heard. Anything in between is an equal mix. Noon is 50/50. When you run other pedals before this device, say a fuzz for example, that becomes the dry signal in the wet-dry configuration, and so setting this knob to noon gives you half fuzz, half downsampled fuzz. Power supply The Knight School Bit Crush only accepts a center-negative DC power supply capable of supplying 9 volts.

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

Amazing - Stop Scrolling and Buy This Pillow
Size: Queen (Pack of 1), Color: White
I have been an Amazon customer ever since the very beginning, and this is my first review. Not because I haven’t purchased tons of amazing things (and a few bad ones), just never felt the need. However, I researched pillows for longer than I care to admit, and decided on this one. I’ve had it for about six months and absolutely love it. No lie, I genuinely look forward lying my big head on it after a long day. I am a side sleeper, but flip flop all around through the night and it’s great in every position. Pros: Stays nice and cool, which is soothing regardless of the time of year. Has a sort of quilted textured pattern on the zip up cover, gives it a luxury feel, that breaths nicely even when a pillow case is added. The fill is fully adjustable to your preference. I knew it came with extra filling but was worried it would not be enough. Wrong. It was very full and I ended up taking some out until it was perfect. It comes vacuum sealed and suggests it may take some time to fully take shape. However, I found it to be about 90% almost instantly and was sleeping on it a couple hours later. There was no unpleasant scent sometimes associated with memory foam items. The foam itself is very nice, a mix of what appears to be shredded and cotton candy cloud like. Very brilliant idea, as it is somehow supportive, soft and firm all at once. The affordability of this pillow compared to some of the others in this category can’t be overstated. Oh, and the packaging was very thoughtfully and securely done. If you are like me, an over thinker, I would suggest just taking this for a spin. It’s amazing. I’m not a bot, or working for the company. I’m just truly satisfied, love this pillow, and have been sleeping great.

It's the perfect pillow!
Size: Queen (Pack of 1), Color: White
I purchased this pillow specifically for its customizable fill feature, which allows you to add or remove stuffing to suit your personal comfort needs. Due to the unique curvature of my cervical spine—forward at the neck rather than backward—I require a soft, semi-flat pillow rather than one that is thick or firm. Additionally, I often experience ear discomfort by morning, so a gentler surface is essential. Upon adjusting the fill, I was pleasantly surprised by the generous amount of stuffing included. There was enough to fill an additional pillowcase, and I estimate it could easily create four to five more pillows. The ability to modify the pillow’s firmness at any time is an outstanding feature that makes it adaptable for a wide range of preferences and sleep styles. This pillow has exceeded my expectations in both comfort and versatility. I highly recommend it to anyone seeking a personalized sleep experience.

Good quality pillows overall
Size: King (Pack of 2), Color: White
Got a set of these for my wife and myself as we were struggling with our old pillows. These have some really good qualities and some things we'd like to see changed. First, the good: These are look and feel like they are high quality and made with good materials. The foam itself has a very nice feel to it. We love the fact they are adjustable to add or remove foam. They come with a pretty substantial amount already in the pillow. We appreciate the CertiPur certification. Now the improvements or changes we'd like to see: The foam, while feeling great, doesn't bounce back well if you scrunch your pillows, and so every day you have to fluff and reshape the pillow, moreso than some other memory foam pillows we've owned. One side of the pillow is cooled and you can feel that even through the pillow case, and that's a great thing. However, one side is not cooled and we'd have preferred if both sides were made of the cooling material. Overall, these are good pillows and we are not disappointed with the purchase. They are not, however, our perfect pillows (which do seem hard to find), and at some point in the future will probably make their way to the guest bedroom. We would rate them as some of the better pillows we've tried and feel most people would probably like them.

Perfect Pillow
Size: Queen (Pack of 1), Color: White
These are the best pillows ever. You can adjust the firmness or softness to whatever you want. For years i used a soft latex pillow , which you cant get anymore. I will never use another pillow. I have purchased 6 of these after the first one. You pick your own comfort level. Best ever. No more neck aches.
