I had the privilege of using this with a Markbass 2x10 cab, and the volume and clarity through all ranges of the instrument was astounding. The amp belonged to a former member of Aranda, who described it as his new favorite gigging amp. I was playing with a basketball pep-band which consisted of about 25 members, and I never had to turn the volume up past 1/4. Aside from the incredible performance of this head, it's very compact as well. I've played several bass rigs since then and none of them even come close to what Markbass has going. I cannot recommend this enough.
