Vintage 1970's A/DA Flanger—"Holy Grail of Flangers!"—Not a reissue! - $625

Hard to find original edition in excellent condition at a fair price! Those in the know consider the A/DA Flanger to be the best sounding flanger ever made.
And the new ones just aren't the same.
This is your chance to get ahold of an original! This pedal took on mythical status in the late '70s and early '80s.
Of course it sounds great on guitar, but with its super-versatile controls it's also the ideal flanger for bass, keyboards, or anything else you want to run thorough it! It sounds amazing! Just as you would expect.
Made back in the day on Fourth Street in Berkeley CA.
Controls include an Even/Odd Harmonics switch and knobs for Threshold, Manual (center point), Range, Speed, and Enhance (feedback/resonance).
The threshold control adjusts at what input level the effect will kick in and the odd harmonics setting produces a killer out-of-phase sound.
Audio in and out, plus a unique TRS "control" input for sweeping the center point externally using a pedal or other devices.
The TRS control jack can be used with 10K- to 100K-ohm resistance (using the +5 volt output from the tip of the TRS jack) or with 0 to +5 volts from an external voltage generating source.
Modular synth folks can go crazy with this! I am the original owner.
The insides have never been touched.
This thing is built like a tank.
And the case is in better condition than most.
It even has all four of the original rubber feet intact! Get it now.
Once it’s gone, it’s gone.
