I'm looking for "one size fits all" amp that will be used primarily for solo practice, but I'd also like to use it in a band setting, and maybe for some bar gigs. All genres -classic rock, 80's rock, funk, soul. I tried the stack out and LOVED the tone, but I'm just not sure if there would be enough headroom for a drummer and electric guitar. Does anyone else use this stack in a (non-acoustic) band setting? Would I be better off just spending the extra $200 for the PF-500 Portaflex stack?
