That's signed by some members of different bands, the most prominent ones are Sum 41 and Breaking Benjamin.
However I don't recognize all of the signatures on it, so I was wondering if anyone could possibly give me a hand.
Here's a link to an album with the pictures of some of the signatures, and the guitar.
Who's signature is the Breaking Benjamin one? (The signature says Breaking Ben under it)
Any ideas?
