I've made a couple of "lifeless sound" threads before and now I'm at it again... But please read anyway
While I do get "good sounds" out of the Kemper (I use SPDIF connection) I noticed today when comparing back and forth (several times) between my interface headphones out, and the Kemper headphones out (usually I don't use headphones, but I did it now for the experiments sake) and I do think I can hear a difference!!!!!!!
I haven't done this before, but I think the Kemper Headphones Out sounds better than the headphones in my interface. It's a Tascam US-144mkii.
I always have trouble getting a kickass metal sound... I look for some free Kemper profiles that sounds great on the preview clips. and once I install and try them out myself, they sound like shit.
So I'm definitely doing something wrong, because so far, I've only liked 2-3 profiles, and they are all 5150s, and one I use most, is actually the stock TAF \m/ Van Halen
But still, I keep comparing my recorded guitars to album guitars (lloaded into my daw) and I never get a sound that's remotely as sharp, cutting and define!!!! Doesn't matter how many profiles I try!!! There's something dull, and cranking the treble/presence doesn't do any good either, I know I shouldn't take them to 5.0
This reminds of this thread:
Kemper Main Outs sound different (worse) than headphone/monitor out
