JJ ELECTRONICS EL844 single

EL844 is a lower power version of EL84. It reduces headroom by approximately 25% which allows it to achieve overdrive at lower volume levels. JJ Electronic has introduced an EL84 tube with a twist! The new JJ EL844 tube provides about 25% less headroom than a traditional EL84, but can be used in any EL84 tube amp without modification to the amp. If you need less headroom for your bedroom amp consider the EL844 tube.

Because the tube has less power to give, you end up with very nice distortion at lower volumes. At the same settings the distortion was now very nice. The EL844 adds a bit of compression so the distortion was smoother and more focused. These tubes have excellent response to pick attack.  Replacement for most cathode and fixed biased EL84 amps.
