12 electric guitars, 2 electric bases, and 4 acoustic guitars (1 of the acoustics I see myself simply as a caretaker for if/when one of my kids wants it. It belonged to their great-grandmother who can no longer play it).
So 18, but soon to be 19, as I have so many spare parts that I'm a body short assembling a parts guitar. The Mrs. has not approved an even 20. She reminded me that I said #17 was the "last one" but I had also reminded her that #18 was an inevitability when the right one hit the market.
