These profiles are must buy. I have permament tinnitus due to using JMP 50 for many years and Bert's profile sounds and feels incredibly close, minus bleeding from my ears.
I am not that familiar with Bassman, but the profiles sound good, very clean, full tones, my Silver Sky loves these profiles.
Soldano is spot on as well. Super musical. It's uncanny how all these profiles react to pick attack and volume/tone controls.
I truly don't need tube amps anymore. I have them in storage, they smell nice, but the tones I am getting from Kemper with good OS10 profiles are 99.99% there. Just don't play too quiet as we can't re-model the physics, if you hear gutar strings ringing that's too quiet.
