You're bidding on a vintage 1960's car radio verb-a-tone Reverberator. I'm no expert on these but from what I've found this added reverb to the radio and also acts as a fader from front to rear speakers. The unit is untested. It is an estate find. The knobs turn and function as they should. Looks to be in good shape with one small nick in one of the knobs and some light pitting on the big chrome stereo 68 plate on the front of the unit. Nothing major, only mentioned for an honest description. Great vintage rare accessory for your hot rod, classic car, rat rod, etc. I'm not sure what makes and models it fits so please do your research and check pictures for your application. Please look at all pictures closely and ask any questions before bidding as item is being sold as is. PayPal is my preferred method of payment. Good feedback is returned promptly.
