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.
The 12AX7EH provides high gain with ultra low noise and detailed, musical tone that rivals the most desirable NOS types.
Sweet and warm sounding preamp tube with high gain.
We recommend this tube for guitar/bass amps
The Ultimate 12AX7. Big, warm, and musical. High Gain, ultra-low microphonics, and superb linearity with a dynamic 3-D sound.
The Sovtek 12AX7WC has a little bit more gain than the Sovtek 12AX7WB and the 12AX7WA. The noise floor is still pretty low compared with other 12AX7 tubes and the dependabiliyt very high.
