From the pics, the wood looks clean, but I'll eat a Spoiler if this is 'used once, like new': The brass needs work (not unusual, but this looks more than 'used once', look at how dulled-out the logo is), and the plated tuning keys' buttons look like that one use must have gone on for quite a while . . . and ads that only reprint the brochure copy with no personal notes don't do it for me.
I've not kept up with Essence prices, so maybe someone who is up on them could advise.
