The JJ Electronic E34L adds more power to a standard EL34 due to its higher grid voltage rating. This increase gives the tube more headroom and a tighter response on the low end. The wide frequency response of this tube offers excellent harmonics that work in a variety of genres ranging from the cleanest cleans to rich and aggressive breakup.

These tubes should work well in the Marshall Superbass though they will be running slightly hotter than rated. In instances such as this you may have shorter tube life but they should sound great.

These have a distinct 6L6GC tone to them. They have more headroom, less break up, and less compression than an EL34. They are maybe a little like a 6CA7 too. They are another unique JJ product with it's own sound. Watch your plate currents and make sure the tubes do not make any weird changes in the first few hours of use. Like most JJs, they are a heavy duty looking valve with a thick glass envelope, and fairly well constructed plates. They also have a sound that is all its own, and there is little if anything classic about it. I know at least one person who is still consulting for JJ, although unofficially. As he puts it, "JJ marches to the beat of their own drummer". I will at least give JJ a nod of approval for not trying to sell their customers on the misrepresentation of "faithfully reproducing the famous _____ valve right down to the finest details". We can tell that is either not true, or they are not trying very hard, so if JJ wants to do something unique, why not? At least we won't be disappointed when it sounds like absolutely nothing else ever made, and it probably won't blow up either.

JJ EL34 gives my JetCity Picovalve the "Vox" chime I was looking for. Great tube at a nice price!
