The preamp is tube, well mostly from what I can tell, they usually have one 12AX7 Tube in the preamp. However, the rest is solid state. As for how it works...no idea

Usually the preamp tube plays a minor role as well, because itīs often run at low voltages where it doesnīt really do anything but look good

Canīt remember which one it was, but Iīm certain that there used to be a Valvestate head a long time ago (>10 yrs) where you could actually remove the tube and hear no difference

I have a Fender Cyber Twin. It has two 12ax7 (spelling??) tubes as a preamp. I think this gives some improvement in sound over other solid state amps. However, you are not getting a full on tube amp by any stretch of the imagination. Don't think that any hybrid is going to sound like a Marshall or Krank. I got mine because the price was right and it had a wide array of clean sounds.

I got an AVT. Kills the Marshall MG and I love the tone. Obviously it's not a full tube amp but its better than pure SS.

Whilst hybrid amps arn't actually REAL tube amps, out of all the tube pre-amp/ss power amps I've played through/heard, the distortion has sounded much smoother than the straight up transistor amps I've encounter.

Perhaps it IS all a marketing gimmick but tonally I wouldn't exactly jump at classing hyrbid amps in the same league as their solid-state cousins.

an AVT sounds better to me than an MG (some people prefer MGs over AVTs though).

however i have to say AVT hybrids are -nothing- like their full tube, more expensive counterparts most of the time.

the tubes for the most part are just a replacement for a clipping diode. allows for a bit smoother operation and thats why its not THAT fizzy sounding
