Hi!
Finally got my powerhead and i am very happy with it, i first bought a regular kemper toast but regret i didn't bought the powered one.
Tried my first kemper through a solid state amp and sounded great, also tried it with a few tube power amps but for me that sounded bad, i guess you could eq it to sound good if you really want.
But i must say for me it is much harder to get profile that sound good through a guitar cabinet, in my case i use mesa boogie rectifier 2x12 v30 and what i experience is that for my liking a profile 1/10 sound good. (the others sounds good through monitors)
in this case it seems very important how the profiles is done, i also experience that profiles done with multiple mic's seems to get it worse?
The best results i got is when using profiles done with the cab i'm supposed playing with, i could use a lot of great profiles from others that may work, but it looks like profliles done with simular cabs seems to sound best, at least for me.
I could probably get many more profiles to work but that seems to include a lot of extra eq, i understand that this is required to get the most awesome sound and that is ok.
Just wanted to share my thoughts and i am happy to get recommends about rigs that work great through guitar cabs, in my case i most interested in hi gain rigs but use all of them.
