Hi All,
I've been doing Direct Amp profiles and comparing them to the actual amp through the same cabinet.
Here is the key, when playing back from the Powerhead they need to be at a similar volume as the actual amp when profiled to get an accurate representation.
You can still use them at lower volume but generally you will need to raise the lows and highs to get a similar experience.
Believe it or not, some capture methods are better than others, even for DA profiles.
Best,
