Sorry for not replying for a while.
There were some stickers / tape on the case, that's for sure. But all have been removed and I found nothing inside or outside that could indicate anything. The only thing you see is the outlining. It looks like an original case though.
Now I don't want to be a bad person but... I'm playing with the idea of selling it and buying myself a 60s Fender jazz... (dream of mine). I know, why would you.
To be honest, the bass is a beast but she's also really heavy and not good to take anywhere (I wouldn't gig with an instrument this exclusive).
If there is anyone on the forum willing to negotiate a possible purchase or has a (pre-CBS) 60s Jazz they want to trade, please contact me personally. I would prefer it to selling it on Reverb to "somebody", I'd love to find someone with actual passion for the instrument
