Pair of matched JJ EL34 II. Brand new, fully tested and digitally matched.

This superb JJ valve kit is for 2 x EL34 Mark II matched power valves/power tubes from JJ Electronics.

The JJ EL34 Mark II power valve was created as a result of customer and amp manufacturer demand. This valve sets new standards and is a great way of getting NOS quality without paying the price penalty.

JJ Electronics say, “The EL34 II has fuller low mids and low end but does not lose headroom in the high end. It is stronger than regular EL34 but not as aggressive as the E34L.”

Reviewers of this valve have described it as follows:

“Less flat than a standard EL34 with a better attack”, “Excellent replacements for Vintage ’60s and ’70s amps”, “fuller mids and better low ends”. “Fuller and warmer in the bottom end”.

EL34 versus EL34 Mark II: which is best?

How does the JJ EL34 compare with the JJ EL34 II? Well, being a smart guitarist you already know that if one really was better than the other in all scenarios then everyone would switch to the better valve, right?

Of course, they would. So the question is, how come on the forums some people prefer the EL34 and some the EL34 II?

The answer lies in the amp you are using, the guitar you are using and the musical style you are looking for. The EL34 II is certainly fatter in the middle and bottom end. If your amp or guitar is lacking in this area then you will love the EL34 II. However, many amps like Marshalls are already pretty fat in this area already and may not need any more filling out. But then again what if you like your amps really down and dirty?

So, if you are serious about YOUR tone then the only way to find out which is best FOR YOUR SET UP is to buy a pair (or quad) of each and compare how they sound.

It is also worth pointing out that JJ claim this valve is much more robust than their standard EL34. If you have a 100 watt amp and find you are getting through a lot of EL34 power tubes, try a set of EL34 MKIIs instead.

EL34 II guitar power valves – get your amp sounding better than ever.

Whether you decide on the standard EL34 or the EL34 II for your amplifier the sound improvement will be amazing. Old valves lose their tone and their power. So whilst guitarists are very good at changing their guitar strings to maintain the sound, they tend to forget to change their amp valves as often as they should.
