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

What Matchless say about this amp.

“The 40-watt Chieftain employs a tube powered spring reverb and a broad array of tone control knobs.  The classic range of bass, mid, treble, brilliance and reverb controls provides quick access and visual confirmation of 5 tube-based tone-shaping parameters.

Exceptionally loud sound pressure levels can be attained with no appreciable loss of tone. Additional features include an effects loop and a switchable output impedance (4, 8, 16 ohms). 
Sound on the 212 Combo is delivered through two Celestion speakers:  a G12H and a Greenback 25, each specially modified to a proprietary MATCHLESS formula.

All of this is encased in an extremely sturdy hand-made 11-ply, 3/4” Baltic birch cabinet, wrapped in richly textured black vinyl.  The finishing touch is our signature backlit nameplate and control panel, which lets you (and the audience) know when the power is on.

The Chieftain will support almost any playing style and is considered an excellent all-purpose amplifier”.
