So I am actually very new at this.. And I am just discovering that the Line 6 POD HD500 is capable of being used for gigging without the use of a head or cab... And just directly outputting the sound to the venues PA system... Is this for real? I recently saw a band called Twelve Foot Ninja live and they had NO amps on stage... Not a single amp.. All I saw was the POD HD500 and some strange box software on the side.. Not sure if it was to manage their in ear monitors or what.. But is there some sort of trick to this or is it literally THAT easy? Performing without the use of amps? This sounds way too good and easy to be true.
