So I love my AX8. Many things sound great but I wanted to hear about the differences between it and the Kempler systems. I read about profiling with Kempler a lot and just saw Dr.Z released several amps to them. I know celestion does cabs for Fractal but why do companies like Dr.Z, Fender, Marshall, and other amp or pedal companies team up how celestion did and more stuff with Fractal?
