This ZSB was manufactured in May 2014. I am not the original owner. I have had it for about a year now. It looks and works like brand new.
I did remove the stock black feet and put (4) Herbie's Audio Lab Grungebuster Dots in their place
http://herbiesaudiolab.net/gb.htmIt has the Ebony knob and standard RCA jacks. It has none of the volume or switch options
Priced at $225. Buyer pays actual shipping (will use corporate Fedex account for discount) plus any PayPal fees incurred. Will accept PayPal, Venmo, check.
Thanks!
