I'm more a crunch-distortion player. I like clean sounds but never was able to get a good clean sound from the kemper. Bert profiles are the ones I like the most. His clean profiles sound right but as I said, I never played that much with these kind of profiles.
I have all BM profiles, and I bought the clean pack with no very high expectations... I grabbed my strat, loaded the amp1 clean lead profile (just because of the "lead" ending)... and it was the first time the I was able to play non stop with a clean lead sound. I was looking at my strat completely amazed. It's the first time I can play a clean solo with the bridge pickup of my strat!!!
If you are like me, more prone to saturated sounds, though you like the sound of a clean guitar but never find the time to tweak clean profiles to find a sound you feel at least comfortable, this pack is 200% for you. And of couse if you are used to clean sounds, Bert profiles quality is a sure bet.
