New Systems Instruments Quad LFO Phase X ExpanderUnlock the potential of the Quad LFO with the LFO Phase Expander. Each expander gives you three outputs that duplicate the LFO with a fixed phase difference. The first ranges from 0 to 180, the second from 90 to 270, and the last from 180 to 360. Along with the original output, this gives you four phases of modulation. These are easily tuneable to quadrature (all knobs centred), but also any arbitrary phase relationship. You can attach up to four

I have to say, after decades of buying all sorts of pillows, trying to work for me and my short neck, this is THE one. I bought the low profile ones and OMG it is just perfect for me. I'm finally getting a good nights sleep without fighting a pillow that is too firm or doubling a pillow that is too soft and thin. It's also not as heavy as other memory foam pillows I've tried. I hate a heavy pillow. Yet, it isn't so light weight that it gets pushed off the bed easily if you change positions a lot during the night.

I am a life long latex pillow user! The one i typically use is 150+. This pillow is better and less expensive . It has just enough firmness but still soft . I am a side sleeper and it supports my neck perfectly . I am going to buy three more!
