No, but they do sound awesome. They're a digital pre-amp into a valve mini-poweramp into a solid-state poweramp. So you have the versitility of digital, the charecter of valve but the cost cutting of the solid state for the power. Clever idea and they do sound amazing.
As for that headphone amp, would that be useable as a preamp in place of a guitaramps normal preamp or would there be impedance problems. Just that I'd like to learn about how valves work in a circuit and have a solid state marshall I don't like so I thaught maybe I could build my own valve preamp to use instate of the solid state one on that and just take advantage of the Marshall's poweramp.
