(I use #6 since #5 was stolen )
Some (like me) LOVE the sound of the KPA - others like it not so much - why?
What kind of guitar amp guy are you?
Type a)
If you are used to mike your real amps and record it - you'll probable love the KPA!
Type b)
If you use other modeling amps up to now - you'll probable love the KPA!
Type c)
If you are used to real tube amps next to you and use a modeler (or the KPA) for the first time - you may not like it.
It sounds very different!
How to improve your sound?
for type a or b:
To get an even better sound - get better speakers - this makes a huge difference for all your profiles.
for type c:
Basically you have three options:
1)
Learn to love the sound of "recorded" amp tones.
Note:
If you play live via a PA, produce a CD, a video, ... - the audience will NEVER hear your amps tone (only the miked sounds),
2)
Use profiles of guitar amps only - and use a tube power amp and guitar speaker
3)
Use profiles created to sound more like the real amp next to you and use large linear speakers.
I myself am more the type c guy - I love tube amps and my KPA sounds very close to then
