yeah, they're not very deep, and the paint is still there, but still...
A few more for the list:
1. Just bought my first brand new guitar at the age of 16, after saving the whole summer: A kramer focus in glossy black, complete with locking whammy.
Brought it to my drummer friend's house a few days later to jam. Had it in the open hardshell case, on the floor, while I hooked up my amp, and he was doing some tuning on his snare.
He got up to put the snare back into his kit and along the way, dropped the tuning key, where it landed smack dab on the front of my new guitar, just below the whammy. Left a pretty decent ding about 3/8" in diameter. I'm not sure who felt worse... but soon after that I wasn't quite so worried about it. At least my dad could kind of relate.
2. A kid at uni was a fan of the band I was in and was learning to play guitar. I helped him out here and there and he came back to uni with a neon yellow Ibanez Jem he got at a pawn shop for very little $$. It needed a setup very badly, and he asked if I could take a look at it. It was in great shape aside from the setup, the whammy springs were way over tightened, and the action was way low to try to compensate.
I was using his tools, and his screwdriver tip was a bit rounded out. I really had to bear down on it to get the whammy claw screws to loosen up.
As I'm turning it, the springs are creaking, and he freaks out a little bit thinking they're going to come loose and hit someone (yes, he was an engineering student).
He tries to cover them up while I'm turning the claw screws and bumps my arm. Screwdriver slips off the screw and skids across the back leaving a 3" scratch.
Probably still worth a good bit of money as an original jem, and it played awesome when I was done, but man, I felt awful that I was involved at all.
My kids- did you know that you can cut a .009 gauge string with kid safety scissors? True.
3. I build stomp boxes as a hobby. I have a really nice wah from an old dunlop shell that I stripped and powdercoated to use with a new pcb I built. Wah sounds great. My youngest kid asks me what all these boxes are, and I say you stomp on the switches and they change the sound in the amplifier. She proceeds to jump as hard as she can on the wah, isn't impressed by the sound, and fortunately doesn't fall down. But she stripped out the mounting pin to the rack that engages the gear on the pot and now I have to replace that.
4. I used to have a guitar stand in the living room at our old condo with one of my electrics on it. My oldest was a toddler and had a plastic grocery cart that made music, etc and was really helpful when learning to walk. She's cruising along at a good clip and doesn't hit the guitar, but rather a swivel chair next to the stand that had a box with some books my wife was packing up. The box didn't quite fit between the arms so it was just off the center of gravity, and my wife had only left it there for a few minutes prior.
Anyway, the chair swivels, the box tilts, I see what is transpiring and get out of another chair just a little too late. The box falls off the chair, lands on a corner, continues to roll on the corner, and of course hits the back of the guitar. The guitar falls off the stand, just out of my grasp, and lands face first on the hardwood floor. Just a loud smack, a little bit of scuffing and some dents in the floor, but really I was just so thankful that it didn't hit my kid, didn't break anything, and fortunately it wasn't my parker! No more guitars in the living room after that.
