12AX7/ECC83 - JJ Electronics

This tube has a well balanced, colorful tone with strongly defined lows, mids and smooth highs. It allows for more clean head-room than higher gain 12AX7s. In overdrive, it is smooth and strong with well defined lows and mids. When pushed into overdrive it offers clean distortion with well balanced lows and mids. The JJ 12AX7 is well suited for all types of music and playing styles. It is also highly recommended for studio pre-amps and hi-fi gear.

The tube came well packed and on time. Thank you.

These are great sounding tubes. But I won't call them my favorites, because they don't sound the best for my amps (Bugera 22 and a Trace Elliot SpeedTwin C50). They sound good in my amps, but the sound is probably best described as warm and round. I think that tube selection is like microphone selection: if you have a harsh source, choose a soft mic and vice versa so as to complement the source. So, for my amps (at least to my sound taste) I need pre-amp tubes with a little more bite. I chose Tung Sols.

Retubed the preamp section of a band mates Fender Super Reverb RI and like day and night. It sounded better than when it was new.

JJ Tesla have the best sound quality you need to make your amp perform. Plus Antique Supply prices won't break the bank. When you need to re-tube this is the place to shop. Enjoy.

Great product, great price and great packaging. Need I say more? No, because I am totally satisfied with these tubes. No more annoying scratchy sound coming out of my Fender amp.
