Translation: Someone in the accounting department saw that the bass included a gig bag, went postal, and nearly had an aneurysm. So we decided to pull the bag. We didn't want to be responsible for the poor fella dying and all, ya know. Unfortunately, quite a number of basses had already shipped with the bag, so we had to go to the marketing department and ask them to come up with an excuse. Brilliantly, they replied with, "A limited amount of Short Scale Stingray basses were shipped with gig bags as part of an... unadvertised promotion. (wink wink)" So we rolled with that.
And now you know... the rest of the story.
