Thanks everyone. I don't really care about the sig, maybe curious in a very mild way but I'm glad its on the back! I assumed it could have been a TE fan who asked TE to sign the fan's own guitar at some time in the past.
I don't plan to get an amp yet, or maybe ever. I was learning a bit about them, but then I learned that Tekker doesn't have one, and says he doesn't need one because his software will do everything he wants. So I plan to see what the guitar will do - I have absolutely no clue about electrics or amps etc yet.
My recent ebay purchase of that USB interface for recording has a whole lot of software as well, which I haven't even used yet. I hope that's all I'll need. I don't plan on any heavy metal shredding or head-banging....yet
