Vox Cry baby Vintage Wah pedal. sn1636786.

This pedal was produced in 1973, according to information obtained from the Vox Showroom.

This one has a 500mh Trash can style inductor.  The paint is about as worn as you might expect from a 50 year old pedal, but the case is sound, the pedal gear and pinion work smoothly.  The pedal rubber is ok.  All original as far as we can tell.  Overall cosmetic condition is Fair.  One or more of the rubber feet  may not be original.
