Hello, i did my first profils today, on my boogie Mark V. I did them using the slave output, this mean that the speaker wasn't profiled.
When plugged in a Power Amp with a guitar cab, it give very good results (to me at least).
Update : now, i've added the rod king cab... if you plan to use a PA + guitar cab, don't forget to desactivate the cab simulation.

The extreme one is only usable as a rythm. When you use it for soloing you will notice some strange effects, probably generated while profiling with too much gain.
The FAT (clean) one is really close of what i get with the amp on the same cab.
The tweed is a very light tweedy one, very pleasant with a strat
waiting for these ones
