Almost 50 days passed since the 2.6.0 public beta announcement. That makes me think that they are working hard in those profiling issues.
In a way, yes!
I can offer some information. The actual profiling works wonderful. We had two users (including Lasse Lammert) that had bad results with metal sounds. After many tests and some investigation we found out that both use a tube screamer with their amp for profiling. This is not recommended for profiling. Still, with the former profiling you could refine the result to work sufficiently. With the actual profiling, refining to that point is not possible (and was never intended).
It is recommended to use the Profilers Green Scream instead. The results are perfect, when you consider that the range for the original Tube Screamers tone control is shinked to the left half of the Green Scream. That means, the original setting to 1/2 is 1/4 on the Green Scream. We will change this behaviour in a future firmware.
We will have a new public beta probably next week, with the Profiling mainly unchanged.
