I'm so nuts with EQ in the Kemper and in post that all profiles are sounding similar to me. STL has a cab that I like to use. They have great marketing and who am I to go against it?
It doesn't matter how good the demos sound from the seller. Perfect example is topjimi. That dude can friggin play. If you do not have a similar guitar, setup, pickups, picking technique,etc.. It's not going to sound the same. You'll be disappointed over and over.
All IMHO
