Blue glass envelope.

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.

All JJ tubes are now matched using our new Apex Matching System and as a result we would not be able to match numbers from our previous matching system.

The E34L will have more headroom compared to EL34's. You can request "low numbers" when ordering to allow for quicker breakup.
