Hi,
Sometimes I have a problem with getting the right balance between the treble and the midrange in a profile in the same way that I sometimes have with real amps and other modelers. For some musical situation it's just not the way I want it. With the KPA I have found that a slight adjustment of the amp Definition perameter gives me exactly what I want to hear. Increasing it does a little something to the balance of the sound. I can't explain it better than this and this may only be to my ears but I thought I would share it all the same.
Cheers,
Mats N
