The JJ ECC83-S tube has several improvements in its construction from the old ECC83 version.



From our review of this tube: "This tube sports a different plate design than found in most 12AX7's. When you look at them you can't help but think that they must be rugged and good for the musician on the road. The compact plate structure does nothing to dampen their sound or dynamic response. I find them to be well balanced. While not as harmonically rich as others I tested, they do provide high gain without the usual noise and microphonic problems you would expect. This is great sound for your dollar. If you're using a combo amp and find the Philips a little rich sounding, the JJ ECC83 / 12AX7 may be your solution."

Nice General Replacement.

I find that this JJ tube has good sound, but lower gain than other 12AX7's. Its gain is more like a 5751. In a Guyatone Tube Echo pedal, it provided too little gain. If you have an amp that is "too hot" these sound nice, and will calm down amps shipped with hot preamp tubes.

Good

Bought JJ ECC-83S to replace stock Chinese tubes in my ART TubeOpto 8. Sound is cleaner and more detailed. Very happy with my purchase and the speed of shipping. Thanks guys!

Great warm vintage blues tone!

I completely retubed a Peavey Classic 50 2x12" with JJs from The Tube Store.��First, I did the pre-amp tubes, and WOW!, what a noticeable difference and tone improvement the JJs are from the factory Sovteks. The JJs tamed the Lead channel's harsh and brittle sound, The Lead channel before was so harsh that I considered it unusable. (FYI, V2 is the Lead channel gain stage tube in Peavey Classic Series amps.)��The Normal channel now sounds like a blues tube amp. The difference is remarkable from Sovteks to JJs. Along the way I also tried Electro-Harmonix 12AX7s (harsh, like the Sovteks), Groove Tubes (better, but not as good as JJs).��I then replaced the Sovtek EL-84 power tubes with JJ EL-84s and the tone transformation was complete.��BOTTOM LINE: I'm very happy with the JJs and the service I got from The Tube Store. Thanks for the fantastic tone!!

warm yet subtle :)

I resently got hold of a Presonus Tube Pre v2, removed the stock Chinese tube and haven't looked back! My bass guitar sounds much fuller without to much saturation. The colouration seems subtle in some respects yet still strong and distinct! Defintly worth a punt!

Good all-around tube

I used the JJ 12AX7 tubes along with JJ 6L6GC power tubes to retube my old SF Super Reverb in place of the mis-match of cranky old tubes that have been in it since I bought it. ��The JJs added cleanliness and reduced the noise floor of the amp to almost zero -- impressive for a 34 year old amp. ��I lost nothing in the way of tone by going with JJs. The fact that they are inexpensive and easy to find / replace are pluses. ��If you're no longer able to keep old / NOS tubes running in your old Silverface, the JJ's are in my opinion a more than adequate new production replacement.
