Hi All,
With using the Kemper it can be easy to overlook a very important part of what makes great tone besides the amp design, the tubes.
Today's amp manufacturers dont generally provides the best tubes in new amps for many reasons. The simplest being they are not widely available.
Here is the latest power tubes we have in.
Thought I would open a discussion to see what you think.
I have a lot of tubes that I roll to find the best fit. Some amps need it more than others but for me, tubes can make an amazing difference.
Bring the thoughts 
All the Best,
