The AD30HTC sports two dual stage channels with completely separate signal paths. The result is two vintage amps in one. Channel One has a thick, creamy, classic voice that barks like a rottweiler when pushed in to the tone zone. Channel Two has a tighter, springy and slightly faster character with a little more upper mids and a bit more gain. This amp has proved to be so popular worldwide that its specification remains unchanged. It is fast becoming the new world standard for 30 watt Class A valve amplifiers.
