This is a vintage 1980 Colorsound Dipthonizer auto filter talking pedal. Considered by most pedal enthusiasts to be the rarest stompbox ever produced by Colorsound, this particular example also features the upgraded and elusive CHROME finish. Probably produced in the most limited production possible without being completely custom, there are probably less than 10 chrome Dipthonizers in existence. What’s even more impressive, is that this pedal is in MINT 100% all original condition!
With regard to sound, this pedal is one of the most interesting and unique ever made. Perhaps the best of all the auto-wah, auto-filter, talking pedal, talkbox, style pedals, this pedal is much more expressive and vocal than any Ibanez AF-9, Ibanez AF-201, or Electro Harmonix Talking Pedal: (and those are some of the best.)
The “Dipthong/Vowel” dial actually allows the user to to choose between 4 accurately re-created interpretations of the diphthongs listed. In the proper context, it is difficult to discern between this pedal and a talk box. Fuzz/graininess/texture can be added as well, which sometimes accentuates or refines the character depending on the circumstance.
