This is the extremely rare second version (v2) of the Stereo Box. It never appeared in catalogs or brochures and was presumably sold only in limited markets like Sweden and Germany, where ST-800 v2 pop up eventually. In more than ten years of collecting Ibanez effects I came across only four of them.
01/27/2023: ToneHome is still looking for an Ibanez CS-505 narrow box first issue with flying finger side graphics. Any lead is highly appreciated. Other than that we're looking for an Ibanez AD3000 Professional Analog Delay & Multi Flanger. Please submit your offers or leads here: e-mail
