"The Phase II, made in limited numbers during 1970-71, is a vintage FX guitar unit. It includes a fuzz, a tremolo (Animation), and a voltage-controlled filtering section (Formant Trajectories-Parallel, Counter, and Vowel switches). The circuit uses only discreet components. A control panel contains seven switches (light/change color) and four sliders which alter several effects, including fuzz, voltage-controlled filters and gating, combined in a box that unfolds to reveal a rocker pedal and four footswitches. There is nothing out there in today's market that duplicates the animation and filtering possibilities.

Specifications:
- Fuzz (includes voice fuzz)
- Animation - FFM, Fuzz RPT or both and Fast/slow start (switches),
Alter Intensity and Rate with three sliders.
- Voltage-Controlled Filtering - "Format Trajectories": Parallel, Counter, Vowel .

"The Ludwig Phase II Synthesizer is an odd formant filter, phase shifter. It's very large and has a great light display. It's thought to have been manufactured in numbers under 200.

Sonic Youth used it on the song Diamond Sea."

Curious if the under 200 number is accurate. Many have come up on Ebay in the past.

"70's Ludwig Phase II Synthesizer. Listed in the December Guitar World as the "2nd Rarest Effect Ever" and Guitar Player's "#1 Weirdest Effect" this is one of under 200 units ever made; one of the very few known to still exist today."
