If You Were Going to Ship an Electric Guitar ...

[NashVegas]

UPS, Fed Ex, or USPS?

Which has the correct-shaped boxes?

1. go to a guitar store..

ask them if they have an extra shipping box for a guitar.

if it's a decent shop they will just let you have it.

the post office is a good place to ship that stuff, then fedex. ups sucks.

2. However, Some UPS Stores. . .

. . .have musical instrument shipping boxes now. They probably have one that would be perfect for guitar and they bubble wrap the daylights out things.

3. I was just with a friend of mine who shipped UPS

The guy at the UPS store measured the case and said he will fabricate a box for it. I think it was about 25 bucks or so.
I'm not saying this is the way to go, but just sharing what I know.

5. Fed Ex Ground is fairly gentle, UPS Ground can be somewhat rough

Be sure you insure and they will treat it nicer.

Second on visit a guitar store to see if they have a spare box.
