Tone
While adding a more driven tone in the pre-amp stage they're not as bright as a JJ 12ax7. Mixed with JJ tubes seems to give for me a very balanced sound.

Perfect for my Peavy Delta Blues
Installed and went out that night and did a four hour gig. They were perfect. Did a 3 hour gig the next night. Tubes sound great.

Poor Packaging By Amazon
These should come in a small cardboard box. Luckily they arrived unbroken. Amazon shipped them in the original thin boxes they come in, inside a padded mailer. These are glass and could have easily smashed. One of the boxes was slightly crunched but it was on the end away from the tube, otherwise it would have been broken. I haven't put them in yet but if they don't work, we know why.

Known Brand.
They worked like a dream. Made amp sound fuller.

Great Replacement Tubes
These really brought my Fender Blues Deluxe Reissue to life! They provide a real smooth sound to your power tubes and are balanced perfectly for most styles of music. I paired mine with Tung Sol 6L6 STRs and a MIM telecaster with custom shop twisted tele pickups. The sound is exactly what I was looking for.

Delivered what was expected.
Good tubes, well packaged, fast delivery and fair price. Couldn't be a better transaction.

To bad they are less than truthful about matching
They are not matched at all. They all test out at completely different gain levels.

Good quality
Arrived ahead of scheduled delivery. Tubes are operating as expected. No problems so far.

Buen sonido
Funcionaron muy bien en un bugera 333, no tengo como probarlos ni medir la ganancia, pero mejoró mucho el sonido al reemplazar los 3 en la etapa del preamplificador

NOT MATCHED EH 12AX7 Tubes
I would not recommend buying tubes on Amazon. It's a gamble. My two 12AX7 from The Tube Store measured 1400/1400 and 1450/1450 after months of use, so they're definitely Matched and I would recommend tubes from The Tube Store. BUT, I received this trio of EH 12AX7 today from Amazon, and they DO NOT MATCH at all. They measured 1800/1500, 1500/1450, and 1400/1200. The MINIMUM for a good 12AX7 tube in my B&K Tube Tester is 1200. So in addition to being UN-matched, one of them is weak. These should be labeled NON-MATCHED TRIO, picked randomly.

Me marcan menos de 60%
Compre el paquete de tres, en mi probador ninguno me daba más de 60%. No sé si es una estafa, son falsos, usados o qué.
