So I recently came across these Boss "Legend Series" pedals. One named for a '65 DR, the other for a '59 Bassman. Their website has a paucity of information on these items that is not terribly confidence inspiring. On the one hand, they seem like a cheesy concept - drop a pedal in front of your amp and transform it into a Bassman! But if they are good, effective modeling pedals that can be used to go direct and take pedals well themselves, well...that'd be pretty cool. Any thoughts on what these beasts really are?
