Valves for Marshall Bluesbreaker

Marshall Bluesbreaker

Valves for Marshall Bluesbreaker.

The legendary Marshall Bluesbreaker amplifier comes in a variety of options. Be careful as they use different power valves to achieve their amazing tone.

The Original 1961 and 1962 models which were made between 1964 and 1972:

  • 2 x ECC83 preamp valves, 1 x Balanced ECC83, 2 x Matched 6L6 power valves and 1 x GZ34 rectifier valve.

In 1966 the amp was given a major change resulting in the use of EL34 power valves and the rectifier valve was dropped in favour of solid state. The control panel logo was changed from JTM45 to JMP and the bgrille cloth was changed from ‘pinstripe’ to ‘salt and pepper’.

This amp now used:

  • 3 x ECC83, 1 x Balanced ECC83 and 2 x EL34 power valves.

The 1989 reissue which was also based on 6L6 power valves:

  • 3 x ECC83 preamp valves, 1 x Balanced ECC83, 2 x matched 6L6 power valves and 1 x GZ34 rectifier valve.

The 1999 reissue Bluesbreaker II which was based on 5881 power valves:

  • 3 x ECC83 preamp valves, 1 x Balanced ECC83, 2 x 5881 power valves and 1 x GZ34 rectifier valve.

A Hand Wired version of the Bluesbreaker, using KT66 power valves, is also now available which you can link to from here.

Over time (and 1964 was certainly a very long time ago) your valves will lose their tone and their power. A brand new set of valves will get your amp sounding like new again.

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.

About the amp:

So the story goes that Eric Clapton asked Marshall to make him a combo that would fit in the back of his car but was loud enough to play on stage. The rest is history. There are several versions of this amp including two reissues so check which valves are in your amp before you order.
