Why do some sellers choose to black out a portion of the serial number of an instrument they have listed for sale?
They hide it because some people a while back would take the serial number from the listing and report basses stolen when they weren’t actually stolen, even presenting false receipts at times and causing all kinds of pain in the ass because suddenly the owner was expected to prove themselves for some reason. Jammed a number of people up in the forums from what I read, and the blurring serial number practice has stuck. It’s not that likely but still, too many musicians do weird shady stuff when they think they’ll get gear for free. An interested buyer might need to know part of their serial number for year model purposes, but unless you own the instrument the rest of the serial number isn’t something one needs. Unfortunately theft is also always a possibility with any instrument though theives probably usually don’t showcase a serial number at all.
Always take full photos. Highly detailed. Documented and of course s# and any paper work that goes with. This is just good practice for insurance purposes and in case something ever happens to it like theft. That won’t stop dirt bags but it will prove you are the owner and caretaker.
I recall being in a rehearsal studio probably 30 years ago and I read a huge, framed poster that the studio owner put up in the room. I can still picture that poster like it was yesterday ... "The lowest form of life is a musician who steals from another musician" I'm sure the studio owner put that up there to deter the theft of gear that someone accidentally left in the room from a previous session. Luckily, what goes around usually comes around if there's any kind of divine justice.
I'm guessing people are afraid of the photos being used to make a claim on ownership of the instrument.
