Excellent condition Alexander F.13-N Flanger pedal, including the original box. Gorgeous tones, and super versatile with on-board weirdness as well. Clean and functions as it should!
Here's what Alexander has to say:
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 fange never heard in this galaxy or any other.
Controls: Rate: Controls the rate of the low-frequency oscillator (LFO) for the fanger, 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 fanger sweeps down (less than noon) or up (greater than noon) based on the input signal. Mix: Controls the blend between the dry and fanged 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 fanged signal fed back into the modulation. Zero feedback is at noon, clockwise increases the positive feedback for a standard fanger sound. Twist this knob counter-clockwise for negative feedback and a unique “inside out” fange. Mode Toggle: Step: The fanger 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 fange instead of flter. Sweep: Traditional fanging is found here. The LFO for the F.13 is actually a “hypertriangular” waveform, so that the fanger spends more time in the interesting portions of the sweep. Hint: Set the Rate control at zero for “flter matrix” style manual fanging. The Depth knob controls the fange position. Dynamic: This one is kind of unusual, even for us! The fanger 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 fanger will sweep when it hears the input signal. Don’t say we didn’t warn you.
