The JJ Electronic 12AX7 / ECC83 has quickly become a modern classic in preamp tubes. Its rugged design and rich harmonics make this tube an obvious choice for musicians who need a reliable and high quality tube at a reasonable price. The balanced tone of the JJ 12AX7 works well in any amp. This versatile tube sounds excellent in clean amps offering an amazing dynamic response while also proving itself in high gain amps with its low noise and noticeably less microphonic issues than other tubes. The warm highs and transparent lows make it a great choice for any position in a tube amp. The JJ 12AX7 is the go-to tube of many amp builders and touring musicians.

Available with gold pins.

No matter what I always end up going with JJ preamp tubes. They hold up well and are consistent. I like the sound of them better than any thing else.

The JJ 12AX7A is my favorite new preamp tube (vs NOS). Very reliable, good tone, and reasonable price. I have a small amp repair business, and sell a lot of these, with almost no returns or failures. Highly recommend!

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 TUBES DELIVER CLEAR WARM SOFT TONALITY IN YOU TUBE AMPLIFIER. SIMPLY THE BEST.

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.
