I'm running an Axe-Fx Ultra into a behringer iNuke 1000 power amp. To me, it's not loud enough. The band is requesting I use 2 4x12 cabs for live. one for each side of the stage. I am the only guitar player. I'm looking for something better and louder to power both cabs. Looking for an affordable, louder option. Any ideas? Its either this or I was thinking of getting 2 powered pa speakers to do the same thing. Any and all ideas welcome!!!
