Please tell me if I got this right:
Say somebody had a traditional 70s Strat with single coils. Say this somebody profiles a Marshall JTM45. He sets the gain to about an average Hendrix like sound. He refines this profile until A/B reveals no difference - that means: at this certain gain the amp / cabinet is perefctly captured. And the guitar is OUT of EQUATION. It is guitar neutral. Correct?
Now I will grab that profile. Say I do have the ultimate perfectly flat monitors. I also do have a 70s Strat. I will get a very, very similar sound at the same gain. Slight differences in pickup variation and strings, though. But the overall tone is just right.
Say I now plug in my Gretsch, hollow body with blacktop filtertrons. It will sound quite different. But how close will this sound to the real JTM45 and my Gretsch now? If the guitar is out of equation after profiling then it should again be identical. Or very close to that. Correct?
So now why are there profiles like "Hollow body pack" or "single coil pack"? In my (Kemper-beginner's) understanding I dont need such a profile but the hollow body guitar instead or a single coil guitar! No?
Maybe its the sweet spot of the amp during profiling? And this will be different for each type of guitar?
