Best replacement low gain valve kit for Fender 57 Deluxe amplifiers. 

As an alternative to the standard replacement valve kit for the Fender 57 Deluxe amplifier, we also offer this low gain version.

The low gain version features a 12AY7 valve for position V1 instead of the usual 12AX7 (otherwise known as an ECC83 in Europe). The low gain version means you will be able to get greater headroom and make more use of the volume knob. The gain reduction is around 50-60% but still retains the full tonal integrity of the amp.

So this superb low gain valve kit contains:

  • 1 x Selected Premium Grade JJ 121AY7 preamp valve for position V1.
  • 1 x Selected Premium Grade JJ Current Balanced ECC83 (also called 12AX7) for the phase inverter in position V2.
  • 1 x Selected Premium Grade JJ 5Y3S rectifier valve for position V5.
  • 2 x Selected Premium Grade JJ Matched 6V6S power valves/power tubes. for positions V3 and V4.

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

  1. Awesome tone. Surely this is what matters most. The number one priority for any guitarist 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 use the 12AY7 low gain valve instead of a 12AX7 (ECC83)?

Some guitar amplifiers (particularly the Fender Blues Deluxe, Blues DeVille etc) have WAY too much gain on the front end for many people’s tastes. I often hear the complaint that guitarists can’t get the volume off 1 or 2 before being deafened!

If this is you, then there is a simple solution. Just swap V1 for a 12AY7. Your V1 will be a 12AX7 (ECC83) with a gain of 100. Swap it for a 12AY7 (with a gain of 45) and suddenly you can get the volume control off the bottom rung!

You’ll also notice less noise from the amplifier. Some say the 12AY7 is also ‘warmer’ with more bottom end, but these things can be very subjective.
