Yeah, ideally I'd want some tubes with alot of ... sparkle, chime, liveliness to them. Some "edge". Brash or not; I think the amplifier can be on the "dull" side of things anyway...
happy for any tips coming in! .If somethings important- send a PM. I might be offline for long periods. Rock on!!!

There are many TAD relabeled tubes, but IME, TAD EL84-STR's are the clearest, least stuffy, most open-sounding EL84's I've tried. My EVH can easily get too low-middy, especially with the stock JJ's, but even with the brighter Sovteks or EHX's. Only the TAD's have made it sound manageable without too much stuffiness. So if you still think your amp is dull with those, I really wouldn't know what else to recommend.

I don't think JJ tubes are all bad. Haven't had any reliability issues with their preamp tubes. I have never had a preamp tube of theirs fail at all. Hell, ECC83S's have always had the least microphony compared to any other 12AX7 I've tried. That being said, they are definitely not my favorite when it comes to tone. Not as high-gain as everyone says they are either, IME. Their ECC803S's are pretty nice-sounding, though.
But their power tubes have had the most failure rate out of any others I've tried. In fact, I've never had any power tube fail that wasn't a JJ. Their E34L's blew a grid resistor in my old Peavey. I've had two EL84's of theirs from different sets fail in my EVH. Their EL844's were fine, but they didn't really sound all that great. Their 6L6's have been alright, but I don't like their tone either.
Their 6V6 sound nice. They are most open-sounding 6V6's out there. They're definitely not traditional-sounding 6V6's. I did have one blow up on me, though.
I am not a snob when it comes to tubes. I just don't usually recommend JJ power tubes. I don't have any 6V6 amps right now, but I do dig their 6V6's.Last edited by Rex_Rocker; 08-08-2020, 09:08 AM.

*EDIT* they say so here: https://shop.magicparts.com/

I honestly hope they are able to pick up production sometime soon. I don't want the tubes that I like to become hard-to-find.
BTW, these TAD STR's are the same tube as the Ruby EL84C.
Oh, and have you tried the TAD STR blackplates? I'm curious about those. I dig EHX ant Tung Sol EL84's better than Sovtek EL84's, and they seem to be sort of along those lines of the same design, just with a different plate coating. I wonder if the TAD blackplates are even more open-sounding than the standard greyplates. I don't find the greyplates all that 6V6-like, personally, since I don't find their bottom-end is bigger than EHX, Sovtek, JJ, etc., but I do find they have a lot less clutter in the low mids and some nice airiness to the top-end.Last edited by Rex_Rocker; 08-08-2020, 10:29 AM.

You would be talking about the inherent characteristic of the EL-84 tube as a whole. Its not the worlds best tube for guitar amps. Not a fan of that tube. Rock amps in my 45 yrs experience sound the best with EL-34 British & 6L6 American. And of those there are tons of CP tubes that sound terrible.

I have a bunch of EL84 amps and love the way they sound. Most of mine have either JJ's, regular 6P14P's or NOS RFT's (dark and low-middy like JJ's...but even thicker/warmer/better sounding...)Last edited by Phantasmagoria; 08-08-2020, 09:07 PM."Less is less, more is more...how can less be more?" ~Yngwie J Malmsteen

Marketed as a "El84 replacement, that will give you less wattage, earlier breakup, and is a direct fit".
...
Sounds like something I could have an use for. But different people on different forums etc. have different opinions.
What are your thoughts about this?
I always run my 20w Blackstar on the "2watt" setting, and even then, it's too loud to crank- as I live wall-to-wall with a neighbor in an apartment.
Thank you for any answers and replies.

There is a 33.33% chance that any given tube you buy whether it says JJ on it or not was actually made by JJ. So saying JJ is this or that is kind of just saying that 33.33% of the world's tubes sound that way. I don't disagree with your impression of them, but just be aware that if you buy a set of tubes that say Mesa, GT, or Fender on them, there is a high probability that JJ made them.
As to the wattage of amps, there is a bit of a misunderstanding of wattage and how it equates to volume. A doubling or halving of power will either increase the volume or decrease the volume by 3db. Now, 3db is not a huge amount. It is not enough to get you into trouble or keep you out of trouble. I would say 3db is only enough for the majority of people to notice a difference in level. 6db is where you really start to have obvious differences. So if you have a 20-watt amp, and you cut the wattage down to 2 watts, that would be roughly 3 generations of reductions or about 9-10db of volume reduction. The only way to get any quieter is to go to 1 watt, which would be about 12db worth of volume reduction.
As you can imagine, it is difficult to cut enough volume from the amp and keep it in the fun zone. Now, these don't say less wattage, they simply say less headroom. Their marketing suggests that you will reach saturation 25% sooner than a standard EL84. If that figure is true, then with an amp set to 2-watt mode, it should be able to achieve similar saturation at a lower volume than an EL84. This is probably a good thing for most bedroom players. If you don't have a wattage reduction switch in your amp, I don't see it being possible to really get into the fun zone at a reasonable volume with these lower headroom tubes, at least not significantly.
