Nice

These are a well made tube like other EHX stamped stuff I have used (I have only had one bad one and that was a microphonic 12ax7eh). No rattles out of the box unlike some JJs I have had. They are punchy and add a nice rounded feel to a driven tone when you push them hard, almost like a really mild fuzz but creamy and not brittle like a Sovtek can get. I like them a lot. El84s all seem to rattle a lot in a combo but so far no issies with these.

Great sounding tubes

Just had 8 of these put in my acoustic masterpiece AM-201H and wow. Compared to the OEMs, for which I could not find the manufacturer, these Tubes have higher highs and better bass response. I'm a happy camper.

Crate VC50 Head

Nice sounding tube. It got everything I want for this type of tube. Going to get a set for my dad's old Vox AC30 (65 mod) soon.

Vox AC4C1-12

The JJ EL84 sounded loud and shrill. JJ 844 was too compressed. Sovtek full but a tad shrill. The EH very musical, tamed the highs and was my favorite of the four.

Excellent in Peavey Classics

Put these in my old Classic 30 along with 2 EH 12AX7 and one Tung-Sol 12AX7 on the clean. Sounds awesome, thick and very musical. Much better than JJ. Peavey Classic with JJ sounds odd and never satisfying, but EH sounds great for the price.

Very good tubes

I installed these in my Tubemeister 18 Head & Voilà...these tubes are very well balance...Better than these tungsol tubes....

Long lasting tubes

Years ago I replaced a set of JJ that went bad on me with a quad of these in my Classic 30. While the sound of the JJs was a bit sweeter and more harmonically complex, they lasted months while the EH EL84s lasted YEARS. I just replaced them with Tung Sol because one went bad. The Tung Sol are little brighter and have more juice, but they're also new so some of that's to be expected. Anyway, these suckers took the heat and vibrations of my Peavey C30 for a LOOOONG time. If they're still made that well today, the price for a matched quad is a bargain. If the Tung Sols can't take the torture in my amp, I'll get another set of the EHs.
