Features: a tube-emulating pre-amp and a solid-state pre-amp.

Now one cool thing I am not familiar with is the Tube Emulation and Solid-State Preamps

With the tube and solid state pre's u can really get some great sounds

The ability to dial in a virtual tube tone or mix that with a solid state tone is another plus

I choose this amp not only because of its power (rated at 350 watts into 4 ohms, but I haven't come close to testing that!), but I love the twin Pre-Amps that blend tube with solid state.

On this head the volume control works as it should
