I have been using the Kemper toaster for 2 months now. My amplification is a RCF monitor of outstanding quality.
I play nylon string (bossa nova) steel string (ragtime) arch top (jazz) and a custom build Lefty Taylor for my cover band (Steely Dan, Toto stuff).
So far I got remarkable results for all types of music that I play, both studio and live. I had to promise my technician and fellow musicians to never ever sell the Kemper ever. Because they really like the sound. Ans so do I.
Besides some acoustic profiles I merely use the famous Morgan profile for my clean electric work. I use the Bogner Shiva for lead (it sounds better than the Bogner I once owned).
So far I use free profiles from the Rig Exchange and I really took the time to sort them out.
Still I have the idea there must be better crunchy and hij gain Profiles out there. I am not looking for the scooped metal hi gain sound but for a fat lead sound like Gary Moore on steroids. And a nice warm crunchy sound would be welcome as well.
Does anyone have experience with commercial rigs in this field and do they sound better than the free rigs ? I downloaded dome free Profiles from M Britt and they are nice but not better than the above mentioned free rigs.
