  1. Awesome tone. This is what matters most. The number one priority for any Marshall owner has to be the tone. Warm, rich, fat and juicy are the words that best describe the sound from these valves.
  2. Sustained valve/tube power to make the most of every stage in the amplifier chain. It is the balance between volume and tone that distinguishes a great valve from a mediocre valve.
  3. Long valve/tube life.  Guitar amps by their very nature have to be built to take a lot of knocks. This is also particularly important when it comes to the amplifier valves themselves.
