The input on my semi-hollow guitar (Epiphone Sheraton) fell into the body. How do I get it out?

Answer 1

Try to shake it out.
If the hole is big enough to get your hand in you can take the strings off first.
There are a lot of ribs on the inside of a guitar, so you will have to turn it over a lot of times, till you can reach it.
I had a full acoustic guitar and have dropped in guitar pics and alike. I did get all of those out, but I am not sure about your input (as I do not know what it looks like and how easily it will damage.)

Answer 2

You mean you swallowed it? God man, get yourself to the emergency ward. They'll know what to do.
