Some people play without picks, but they're... odd.
And as ghosty says, an unplugged electric guitar is just an unplugged electric guitar.
An acoustic guitar is a bit different.
Electric.
Acoustic. (Bearded chap optional)
EDIT: Hmm, apparently you don't always get the bearded chap when you load the Martin site. It seems you need to look a little strange to play a Martin though...
