The common MOSFETs, IRF511 etc., are enhancement mode devices. The key to getting the MOSFETs to sound like tubes is to use depletion mode devices. I have several on my work bench that I plan to drive with a high V+, 250-300v, and see if I can get some tube sound.
Let's see, if I remember correctly, the higher the gate bias voltage required for turn on, the longer the linear part of the channel will be, which I think will give you a longer region to make the turn-on (ie: soft clip).
Also, I'm designing an FET Big Muff... should be interesting.
