Shad, Hotter and fatter than the regular JJ, this tube gives more headroom once in the circuit. Creamy tones and great low end.Sounds similar to the "normal" JJ 12AX7, but the overall sound is more fuller and powerfull with a bigger bass. In comparison to its litte brother
JJ12AX7 the JJ ECC803 also has much bigger plates and draws much
more current if used with standard 12AX7 parameters. The quality of this
tube is absolutly OK and it is suited for instrumental amps as well as audio
and / or HiFi Tube-Amps
Highly recommende also for use in so called HiGain-Amps where the
sounds are often a little bit cold and harsh.
