Hey man, I know you are not really in the area but Matrix amps will be in Birmingham on July 12th at a rehearsal studio And will have a number of Matrix frfr solutions as well as a couple of the most widely used competitors. There will also be standard guitar cabs to compare. You can also try the full range of solid state power amps along with AxeFX2 and I'll be throughing my KPA in the car too. Should be a great evening.
Its on their Facebook and I'll post a link tomorrow.

Are you sure they'll let you in with your Kemper?
Make sure you have a body guard with you, you might need one.
