Oh really? Thanks for you answer!
I have the same problem as Popes666 (really flat and thin sound, buzzy distortion like a bias fx sound or others, never anything compare to youtube videos...)
I am connected in XLR on my Yamaha HS7. I’ve tried to connect kemper directly, or by the soundcard (presonus audiobox) but it’s the same result...
Maybe the sound can be good only with guitar cabinet? But in many cases people seem to have good sound with stereo speakers! :
In this vid rabea uses a marshall 79 profile by M Britt, i have it in my kemper but never sounded as good!
Do you think spdif is very mich better on stereo speakers?
