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.

I replaced tubes in an old dead Crate Vintage Club 30watt with the JJ 12Ax7's and JJ EL84's...WOW!!! It's never sounded this good. Im even going to say something I can't believe, I played thru a Kendrick New Joyzee I had Gerald Weber built until it got stolen, but this little 30 watt is driving warm all the way to SMOKEN!!! And this will be my amp until I get brave enough to build one myself. I also put a MOD reverb tank in it and its very smooth and sparkly.
Thanks for the great selection of part and supplies and the quick service. OUT of the PARK!!!

These came as Oem in my Blues Deluxe. Loved the sound so I put them in a Hot Rod Deluxe. Talk about warming up the sound. They break up nicely when pushed as well.

JJs are the most highly recommended tubes currently being manufactured. I have had nothing but good results using them. I hope they don't drop their standards.

I put a pair of these tubes in my Morgan and haven't been happier. They help keep my tone ringing clear. This is my go-to 12ax7.

These are the only tubes I use after a 10 year tone search these are the best for tone quality and best price. These are the TONE KING! I've tried them all NOS RCA(way expensive), EH Russian Made (harsh) and Tong-Sol (not impressed). But these JJ tubes are the kats meow! Smooth and musical!

I've had the Bugera V5 guitar amp for a month and think that its a great buy for the money and fun to play through. The overall sound was good. I purchased the JJ 12ax7/ECC83 gold pin preamp tube and the JJ EL84 power amp tube to backup the stock BUGERA tubes.I decided to put the JJ tubes in and use the stock as backups. The difference was very noticeable. The amp now sounds richer with more presence and smoothness. The JJ tubes improved all ranges of EQ and general tone whether I play clean or all out distortion. It was like having a switch that went from good to better.

I replaced the china tube in my ac30vr with the jj and i gotta say i like the result some more clean head room but not to much it still breaks up really nice!!! shipping was great also.

I did not know how much the pre-amp tubes alter the tone and sound of an amp until I put 2 of the JJ12AX7 / ECC83s in my 65 Bandmaster. I have never heard a Bandmaster sound like that. I'm going to put 2 of these in everyone of my amps.

Very good. Not expensive and works really well. The shipping was also very fast. I will purchase here again.
