I've spent a lot of time rocking out on a plastic guitar. I have no problem jamming with my friends, or even doing it in front of a few strangers at a party. But I've never considered the thought of getting up on a stage in front of thousands of screaming fans. Mostly because no matter how good you are on a plastic guitar, you'll never have thousands of fans packing a stadium for you. Well, at least not without a little bit of help.
