  1. Awesome tone. This is what matters most. The number one priority for any Mesaowner 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.

Why Don’t you sell Mesa Tubes for this amplifier?

The reason we don’t sell Mesa tubes is that Mesa doesn’t make amplifier tubes. They simply buy them from the main five manufacturers, of which JJ is one, and then rebrand them. We think they are overpriced.

However, what Mesa does promise is their valves are perfectly matched and biased so you don’t have to rebias the amp. That’s great – and we guarantee that too, but without the hefty markup because we buy directly from the valve manufacturer.
