Tube amps have always been the amplifier of choice for the working musician. Musical myth has ascribed almost magical tone to them. While the results may not be entirely magic, tubes do have a sound that is different from solid state amplifiers, and one that happens to make amplified music sound better to the human ears and brain. There are lots of technical and psuedo-technical explanations for why this should be true, but there is enough solid evidence that it is a real effect to trust it. The real reason to use tube amps is simply that they sound better. For that advantage, we put up with the poor supply of parts, high prices, fragility and excess heat that they produce.
