Well, the Kemper arrived today, only had a short time to power it up and have a go but all seems well so far. Updated it and played through my valve amps cab with a celestion blue in it with some two rock profiles.. sounded amazing, really great. Thanks for the help everyone, just got to order a cab now, I think I'm just gonna go down the normal guitar cab route, tried FRFR in the past and wasn't a fan, not sure I want to bother with the Kone either but we'll see.
Really pleased for you!
I will just say again, guitar cabs add massive colouration. The KPA is there to emulate the whole signal chain and so you make a profile including the cab, artificially remove it and replace it with a real cab - the results are less predictable.
I agree with you on FRFR in that it can be very clinical but not all FRFR's are equal.
The Kone is meant to be a solution in between FRFR and a guitar cab, giving you the best of both worlds. For me it works brilliantly although not the same for others. If you can find a way to try before you buy then I would suggest its definitely worth a shot.
