I would take the neck off any guitar or bass I shipped. For the smaller cheaper package.
As an aside, when I was front house manager at a small winery here I got a phone call from a (claimed to be) lawyer in California. Was irate, and opened the conversation with "Your corking process is defective! I bought a couple of bottles of red wine, wrapped them in my clothes in my suitcase, and when I got home the corks had popped and all my expensive Tommy Bahama resort clothes were stained with red wine! Several thousand of new clothes I bought for that trip ruined! I'd like to give you the opportunity to make me whole without getting the courts involved..."
I interrupted and asked "Sir, I'm sorry that happened. Did you check your suitcase?"
He said "Well of course."
I said "Well, you must not have realized that cargo holds aren't pressurized. At altitude the small amount of nitrogen in the bottle would expand and pop the cork."
He calmed down, said "Gee, I never thought of that. Anyway, I still think your company should warn people when they buy wine to take home not to put the bottles in checked baggage! It's irresponsible and leaves you open to damages..."
I said "You're absolutely right. We should also warn people against crossing the street without looking, or trying to walk downstairs with their shoes untied. Probably should make sure they're putting their seatbelts on."
He was silent for a while, then timidly asked "So, you aren't going to reimburse me for my ruined clothing? I mean, maybe not all of the value, but half?"
I laughed and said "That's the first thing you've gotten right in this conversation. Have a nice day." And hung up.
Guy was from California and wasn't going to come back in anyway, so I had no problem burning that bridge and didn't feel he was a potential return customer.
