Hello everyone! I'm looking to get a new head for my rig, and I'm having a hard time picking one. I have it down to the Mesa M9 Carbine and the Aguilar AG 500. My only experience to these amps is I have played a M6 once at guitar center. Aguilar is not a common amp in music stores so I've never played one but I've heard very good things. I like the 2 channel idea on the Aguilar and I will use it for some songs but I don't know how the overdrive sounds. I need help! I play in a Christian Rock group that has a mixture of heavier(Pillar, Disciple, Skillet) like music to worship music and even to some acoustic. My cab is a Mesa Powerhouse 1200 and i also use a bbe sonic maximizer. With this all in mind, anyone have any suggestions? Thanks!
