Hey Paul:
Mint is used, and a term assigned by the seller. NOS is new old stock. Unplayed, sold as new with full factory warranty. If you buy it, you go into Alembic's records as the original owner. I do not mean to argue with you, but I do not believe yours is NOS. You are a person selling a used item, where the eBay item is being sold by a dealer as brand new. Bottom line is something is only worth what someone is willing to pay for it. A lot of Alembics are on the market at prices that leave them unsold. I find $7,500 to be a good price for a brand new Series I with $3,000 worth of upgraded wood, and if I were in the market for a point shaped LSB 4, I would have popped the BIN and never brought it to anyone's attention here, except to post pix in the Showroon section, later. If it was an omega cut bass, same result, and I would have called it an investment, giving myself a thin 'reason' to have two omega cut LSB 4 Alembic basses. And everone here should know by now, Alembics are bought for love of the instruments, not as investments, as new ones lose so much value as soon as they become 'used' instruments.
