Hello guys!, first of all, this is a personal opinion, as a result of many gigs in many places and working with audio engineers with more... or less empathy.
What I have learned over the years with modelers, and now with Kemper, is that... to get the best live sound, it´s not to do a focused job on eqs, compression, etc. What really works great is to leave the amp as natural as possible, using only the EQ of the amp itself, as you would with any traditional equipment.
What often happened to me, when the sound tests started, I used to "argue" with the audio engineer about my amp, that the signal was already coming from my amp equalized, how I like it, but with time I realized that they don't like it, many times they left the signal flat, but outside it didn't sound like it should sound, it could be the place, the reverb, the front of house sound system that has a particular sound, this made them angry, because the sound was very unpredictable and they make some "against eq" corrections that gave a worse sound.
Over the years I have learned from them, from the audio engineers that it is best to give them what they expect, the sound of a natural guitar amp, with its darkness, or high frequencies when they see some Marshall or a Mesa. they know what they have to do to make your sound great, everything changes when you play on a large stage, a "Plaza de Toros" or bullring, a closed area. It's my recommendation, you'll get a better sound with your natural amp sound, I'm not talking about effects, obviously.
Best is leave the guitar sound treatment for the recording studio sessions, although sometimes we confuse sounding a guitar with "that sounds like that album that I like", which was also recorded 20 years ago , haha, let's not forget that the same amp and guitarist sound different in different albums for many reasons, mixing eq, master eq, studio equipment. etc.
Anyway, I hope that with this advice you enjoy a pleasant live experience with your Kemper, and... get along with the audio engineer. : D
