Additional Information

Manufacturer JJ
Shipping Group No
JJ-Electronic Valve ecc83s Is great for blues/rock players, good fat base. This tube clips slightly earlier than other 12ax7's giving you that edge. Tested for shorts, balanced triods, audio test so you get the best of the best.

We offer three price options:
1) Factory tested from the JJ factory
2) Premium tested for microphonics, shorts, leaks, triod balance and audio quality
3) Tested for V1 and Phase Splitter positions
  1. JJ 12ax7 Review by ChrisM

    Installed in a marshall dsl 50, not a bright tube like a philips ECG or RCA. The JJ can sound quite dark in some amps, but breaks up quicker than other 12ax7 types with a nice balanced warm sound... (Posted on 21/11/2012)

  2. Review by MarkB Review by MarkB

    Great valve for V1 or the PI socket. If you use a lot of pedals you might want a lower gain valve, but in this VC30 that had a dodgy old Mullard in V1, brought it back to life big time! (Posted on 31/08/2012)

  3. Brilliant Review by Martin

    Bought to replace the standard valves in my son's ENGL Savage head as it was producing a significant amount of hiss, these have improved it significantly, even at fairly high volumes you now have to put your head right up to the speakers to hear any hiss, it's so much quieter !

  4. Great Results Review by AlanR

    Installed in a Hayden Mofo 30 along with El84's and an ECC81 in the V1 position - massive improvement over the original tubes. The overall solution improved definition and head room substantially which is exactly what was wanted. Great service and advice from the guys at Hot Rox. (Posted on 29/06/2012)
