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.
Congrats!
Output to a preferred cab/speaker is subjective of course. My journey was:
PRS Custom 50 combo 1x12 into the return of the loop. Good but not inspiring
Fender 80w PA. Better but didn't like dealing with the head and 2 10" speakers
Yamaha DXR10. Excellent. Not many complaints and the coverage was fantastic
XiTone MBritt cab. Also excellent. A bit more guitar oriented and started to flap my pant legs on stage
Avatar 2x12 with V30s using Camplifier or SD 700 class D amps. Also good but not inspiring
Kemper Kabinet with Camplifier or SD 700 class D amps. OK... done... that's it for me. Either stereo or mono, and with the profiled speaker or one of the numerous imprints it has the pant flap on stage, and all the tone and feel I want/love.
Enjoy the journey, and I hope you find your grail tones!
