The JJ Electronic EL34 II is a different construction of the classic EL34 tube that offers a different tonal palette than the original. This tube has a more compact plate structure than standard EL34’s. The JJ EL34 II has an increased low to low-mid end with plenty of headroom to spare. This tube has a thick and tight bass response. The mids are balanced and harmonically rich with pleasantly smooth highs. The JJ EL34 II is stronger than the original but not harsh sounding in any way. When overdriven, this tube has a warm and dynamic distortion that rivals many vintage tubes.
