Tubes enter the saturation zone gradually or softly, which lends tube-driven tone its trademark yet totally unique character.

I remember when i got my first guitar ever for christmas. I got a cool guitar video aswell. The first bit was of dave celentino(i think thats how you spell it). He was doing some 8 finger tapping. It looks damn amazing aswell as sounding good. I have to say i was very impressed with it and i still am.
