Powercab vs Monitors in small studio space in Helix Posted 19 minutes ago Try out the powercab before you buy it. I have a powercab 112 plus and I think it works great as an FRFR and for IR loading but I don't really like the speaker only option as much. This is where the Powercab is supposed to sound like an amp without any microphone simulation. It just sounds strange to me. I've used plenty of real amps and I prefer the sound of the FRFR or IR sims. They actually sound amazing and it's what I use with a live band.
