Product Overview
The depth of low end and forward midrange from this tube is astonishing. It has a level of "ummph" that must be heard to believe. There is so much more tone from this tube that some amps struggle to handle the boost in performance from this tube. This is not a generic low gain 12AX7, this is pure muscle. And if your amp can hold on, it's worth trying in all positions just to see what can be awakened in your amp.
At the end of the preamp tube chain, the JJ ECC803S Gold Pin makes a phenomenal phase inverter tube. Its oversized plates give the additional drive needed to really push the power tubes to their fullest potential. This is pure electrical adrenaline; it's as if excess horsepower was squeezed into the glass. For whatever music you play, this tube will surprise you.
