hello AnnunakiGuitar. Feel free to ask any quesions you want on this forum. If you are into Jason becker, see if you can find some of "justin laylors" stuff on this site. I know he has tabbed out "air" and some of the "altitude" sweeps.
By virtue of their electrical properties, tubes generate a special waveform when they're saturated, which is why tube engineering has tremendous tonal advantages over solid state or DSP solutions, particularly for crunch and lead sounds. Tubes enter the saturation zone gradually or softly, which lends tube-driven tone its trademark yet totally unique character.
