Best valves for Fender Studio Bass amplifiers

The Fender Studio Bass amplifier uses:

  • 3 x ECC83 preamp valves (also called 12AX7) in positions V1, V3, V4).
  • 1 x ECC82 (12AU7) for the EQ in position V2 (see note below).
  • 1 x Balanced ECC82 for the phase inverter (in position V5).
  • 6 x 6L6GC matched power valves/power tubes.

There’s just one thing you have to be careful about when fitting these preamp valves as the layout is different to most other amps. When you look at the amp from the front, the order of preamp valves, from left to right is  V1, V3, V2, V4, V5, V6.

It does not go in numerical order as you might expect.

This is important because it means that the normal ECC82 for the EQ that goes in V2 is actually the THIRD valve from the left.

We always recommend JJ valves for this amplifier. This is because they guarantee you get awesome tone and long life and they don’t cost a fortune.

Remember, JJ is one of only five manufacturers of valves in the world. So don’t pay higher prices for valves from the same factory that have simply been rebranded by other companies.
