Relevant pics from the auction:
Probably similar to the EH Talking Pedal.Super rare Colorsound Vocalizer in box. 9.5/10 condition with original box. Works 100% and sounds AMAZING. These are so painfully rare, and to find one in this condition and in the original box(been buying/collecting vintage and boutique pedals for over 16+ years and I've never seen another).
This is basically a manual sweep Dipthonizer, but WAY more vocal(and a few prominent collectors who have heard this have commented similarly), and way more quite and stable. Has a fuzz control to blend in to dramatize the vocal effect, like the Dipthonizer, but either way sounds awesome...really must hear to believe.
