has somebody got a Rivera KR7 Head? rivera.com/product/heads/kr7-mick-thomson-signature/
Or a Rivera Knucklehead Tre? rivera.com/product/heads/knucklehead-tre-reverb/
I would love to test a amp like this, but found nothing on the rig exchange.
I would also pay for a few good profiles of this heads!
Please let me know if someone got such a head!
