Need a low gain valve kit for your Fender Pro Junior amplifier?

This low gain valve kit for the Fender Pro Junior is specifically designed to:

  • Reduce the gain of the preamp stage of the amp by around 35-40%.
  • More clean headroom for your amp.
  • Give you more room on the volume knob. No more struggling between positions “0” and “1”.
  • Get a cleaner sound.
  • Helps remove any “Fizz”.

This superb JJ valve kit comprises:

  • 1 x Selected Premium Grade JJ ECC81 preamp valve (also called 12AT7) for the V1 position.
  • 1 x Selected and Balanced Premium Grade JJ ECC83 (12AX7).
  • 2 x Selected Premium Grade Matched JJ EL84 power valves/power tubes.

Please note that the V1 valve is the one closest to the input jack.

We always recommend JJ valves for the Pro Junior amplifier. This is because they offer a superb tone at a very attractive price. We think these are the best valves/tubes for this amplifier. You can order these amplifier valves singly or as matched pairs but it is always recommended that you change all your valves at the same time if you possibly can.

So treat yourself to a brand new set of gorgeous sounding valves today. Restore the power and clarity to your amplifier.

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