A few years ago my friend won a competition to go to a trivium guitar workshop at the KERRANG.radio station in Birmingham. He took me along as a +1 and we got to sit and watch the band play an acoustic set and then got to meet them afterwards. After the session i had my squire stratocaster signed by Matt, Corey and Paulo; Travis didn't attend because it was an acoustic set. I thought it best to post on a fansite and see if there would be any interest in the item if I were to put it up on eBay.

I reckon... and this is just my opinion.. don't shoot me if you disagree.....

If it had been the same type of guitar that the boys use, it would probably attract some interest from fans.
Having a strat signed is pretty much like getting a personal item signed and it's special to you being a fan... and not worth much to anyone else...

You've probably decreased it's value dude...LOL
