I use my KPA exclusively for recording (thru convertors because I work at 48k). I've found that quite often I have to really work at EQing the low end with something like DMG Equilibrium to remove the low end wallow that is overpowering if left in the mix.
I've just played a Strat thru some Profiles I previously made (of late 50's Bassman (2), Bandmaster, Super, Low Power Twin, High Power Twin - made w/ U-67 w/ 55 Strat) with 2.6 beta for the past hour and I am not hearing that low muddy blossom and above that area there is nice power in the warmth region. (Edit: I should mention that all of the profiles are quite clean.) Additionally I am hearing with LFC On (vs.Off) the Profiles giving me a much more balanced cohesive smooth sound overall. Quite remarkable. Even the effects (if used on the profile) sound better ie. reverbs more transparent etc I guess because the guitar signal is without baggage. (Edit: Monitors are nearfield Neumann A-310s).
Edit: All twenty profiles were clearly better sounding with LFC On.
I guess I'll wait for final release and try profiling again but what I am hearing with 2.6 beta is very nice.
Excellent work gentlemen.
