Alien mojo meets military tech, circa 1958.  The F.13 is our take on space junk stolen from Area 51 and put into the service of rock 'n' roll.  Equal parts science, art, weapon and instrument, the F.13 generates interplanetary flange never heard in this galaxy or any other.

 

Controls:

Rate:  Controls the rate of the low-frequency oscillator (LFO) for the flanger, from glacial to space invaders.  Controls the input sensitivity in Dynamic mode.

Depth:  Controls the maximum LFO sweep.  In Step mode, the depth control chooses downward steps, upward + downward steps, upward steps, or random steps.  In Dynamic mode, this controls whether the flanger sweeps down (less than noon) or up (greater than noon) based on the input signal.

Mix:  Controls the blend between the dry and flanged signal.  Equal mix is at 12 o'clock.

Hint:  Pitch vibrato is available with low Regen settings and fully wet mix.

Regen:  Adjusts the amount of flanged signal fed back into the modulation.  Zero feedback is at noon, clockwise increases the positive feedback for a standard flanger sound.  Twist this knob counter-clockwise for negative feedback and a unique "inside out" flange.

 

Mode Toggle:

Step:  The flanger LFO is forced to "step" to eight different values for transforming robot sounds.  Sweeps either up, up + down, down, or random.  The random mode is similar to a synthesizer "sample and hold" effect but with flange instead of filter.

Sweep:  Traditional flanging is found here.  The LFO for the F.13 is actually a "hypertriangular" waveform, so that the flanger spends more time in the interesting portions of the sweep.

Hint:  Set the Rate control at zero for "filter matrix" style manual flanging.  The Depth knob controls the flange position. 

Dynamic:  This one is kind of unusual, even for us!  The flanger delay time is set by the volume of the input signal.  The Rate knob adjusts the sensitivity, to allow for different pickups or effects before the F.13.  The Depth knob controls which direction the flanger will sweep when it hears the input signal.  Don't say we didn't warn you.

Quite good. I am actually surprised. Too small for queensize
Item Package Quantity: 2, Size: Queen
These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning. Update 04/24 These are actually quite small to be considered queen pillows. They have become firm over the last few days.

Full, Fluffy & Perfectly Supportive Euro Pillows!
Item Package Quantity: 2, Size: European, Item Package Quantity: 2, Size: European
These Euro size pillow inserts are fantastic! They’re soft, full, fluffy, and hold their shape very well. The firmness is perfect — supportive without feeling too hard. They filled my pillow covers beautifully and made the bed look much more luxurious. Great quality for the price and very comfortable for lounging or sleeping. Very happy with this purchase!

amazing.
Item Package Quantity: 4, Size: Queen
WOW. I was really skeptical, but the other reviews are spot on: these are amazing firm pillows. I really hope they don't lose their firmness and become lumpy like other pillows tend to do. Excellent pillows for the price!!

These are very thick pillows.
Item Package Quantity: 2, Size: Queen
Exactly as advertised. They are very firm and very thick. They're too thick for me to be able to use as bed pillows. However, they seem to work pretty well as cushions in my papasan chair on top of its normal cushion also work very well as decorative pillows. I'm still giving them four stars because they're exactly as advertised and they seem well made. My only complaint is that they're just too thick. And that's definitely not the fault of the pillows or the pillow maker.
