The differences are pretty obvious... but the only main differences are the AY Sig has an AY pickup that replaces one of the '57s... The tailpiece and the smaller pickguard. Personally I wouldn't want to have a guitar with "ANGUS" engraved in the Lyre tailpiece..... the devil logo is pretty cool though.
