I've been noticing on eBay that the majority of Boss OC-2 pedals and a good number of OC-3 pedals have no sticker on the bottom plate. The ones that do have a sticker DON'T have the serial number sticker. Some OC-2s claim to be made in Japan (but are missing the sticker to verify) and some claim to be made in Taiwan (but are missing the serial number sticker). If it was just one or two every once in awhile, I'd chalk it up to the sticker possibly getting removed when someone pulled the Velcro of the bottom of their used pedal. When MOST of them are missing the sticker--or even more suspicious--when they have the sticker but are only missing the serial number...that's make my eyebrow go up--like this Can anyone offer a legit reason why eBay is flooded with Boss octave pedals with no serial numbers?
I thought the serial #'s were inside, under the stomp plate (where the battery is) on the vintage MIJ pedals. I know I have a few that have it there... maybe that was only on the really early ones. I dunno.
^part of the conspiracy is my guess. kidding, kidding... I could see scammers ripping the labels off. Not out of the question. If the serials are inside though (still not sure, couldn't confirm online, tried bossarea.com) then it's moot because you can always check the date based off that.
Any decent scammer or pirate would try to make things look as right, including a faked label, I would think.
Labels are expensive. To print a one-off foil (silver with black text) label might only cost $1.50 each, but you have to buy a roll of 1000 blank foil labels, and a special printer, and special ink. So you might pay $5000 just to be able to print that one fake label.
My recollection is the PCBs are clearly labelled with their country of origin. I bought/sold a handful last year and some of the pedals with Taiwan stickers on the bottom had Japanese PCBs. If you spend some time searching you should be able to find a thread where I posted some pictures of the two different PCBs for easy identification, probably in the "OC2 synth mod" thread.
The juice wouldn't be worth the squeeze . Anyone who bought the pedal, that could actually discern the difference between mit and mij, could just look at the circuit board. If the scammer made a fake label, it would cost them more to make the label than the extra $ they would get
+1 All my vintage MIJ have the serial numbers on the inside. However, I don't know when Boss started putting the serials on the bottom. Just avoid buying pedals on eBay if you think it's a conspiracy?
