ive already done a lot of research on the genz head and its definitely a contender. i started reading about mesas and everyone seems to love them. im looking for a head that will do old school tube groove as well as new school slapping and tapping. my only question is would a walkabout or mpulse 360 be loud enough for a really loud modern rock band that adds a touch of metal? ill be going against your typical half stack and a very LOUD aggressive drummer. my speakers will most likely be 2x12 avatar + 2x10 avatar. i havent wrote off the possibility of a an eden metro combo with an additional 2x10 xlt cab.
