Well, im 17 in just under a week and have been playing guitar for just over a year now. I am still having lessons and i think you can never be too good not to. I have never played infront of many people only about 4 people at the most.
I know these kind of questions may have been asked before, but i love finding out about other people :)
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.
