SeM20 Filter Single ChannelThe SeM20 is a 2 pole state variable filter loosely based on the Oberheim SEM's filter with the resonance section of the MS20 grafted on for extra bit of grit. It won't self oscillate, usually, but with an input, or the High Pass out plugged into the Input, it will howl. The Input section is set up much like the input of the OSCar, when the input is at 5 it's full volume. Beyond 5 the filter will begin to overdrive and distort.

I think this is the perfect weight. I am a “hot” sleeper and I slept comfortably all night. I was really surprised at the quality of this product at the price I paid. I did not wash it before use because I put a duvet cover on it but the quilted, baffled construction should stand up well to washing as shifting of the fill should be limited. Overall an excellent choice.

Better quality than more expensive products.

Color: White, Size: Queen

I bought this for a bed in my air BB space. Renters appreciate white linens to ensure clean and crisp feelings. Honestly I didn't have high expectations because of the low price but I was pleasantly surprised. I threw it in the wash and it fluffed up nicely. It's he perfect weight and the fabric and seams are all high quality. I don't currently use a duvet covor on it but the tabs seem sturdy if I wanted to. The design is well thought out and the price is even better!! I ordered a queen and it's size is perfect for winter or summer and still fits in my 4.7 cubic foot washing machine making it easy to use and clean between guests. It didn't have a strong smell out of the package and didn't smell at all after a single wash. I will definitely be ordering more for my other beds.
