TUBE ROLLING WITH A HIGH GAIN / HIGH DISTORTION AMPLIFIER:
Years ago, I acquired a small amount of vintage 12AX7 tubes.
I also purchased 5 or 6 different brand new 12AX7 tubes .
They all passed the test on my simple Orange VT1000 tube tester.
I then proceeded to roll tubes in my vintage 2204, with the preamp volume turned up high.
After spending an entire afternoon, testing sound quality between different tubes, I remember walking away scratching my head....
No matter what tube I installed, there was no significant difference to my ears!
In other words, there was not 1 tube, that I thought sounded superior to my ears.
I remember thinking at the time, that if I did a "blind" test, I would not be able to pick out any 1 tube that was superior.
So fast forward to today....
I added a few more brand new tubes to my small collection.
So I now have maybe 15 different 12AX7 tubes, both old and new.
Again, I pull out the my tube tester, and they all pass the simple Orange test.
So today, I sit down with a decent amount of different 12AX7 tubes, both old and new production ...
This time however, I use a different amp, thinking that simplicity would prevail.
So today, I choose a 5 watt Epiphone Valve Junior, which only utilizes 1 preamp 12AX7 tube.
Think poor mans Fender Champ. Similar but different.
My thinking was that by using the Epiphone Valve Junior amp that utilizes only 1 preamp tube, the differences between different preamp tubes would be much more pronounced.
Again, I spent several hours rolling tubes in the little Epiphone, with the volume up 3/4 to 100%, which is exactly where I like.
And once again, despite having many different tubes at my disposal, I walk away with basically the same result...
There was not 1 tube that was clearly better to my ears, than any of the others.
Again, I feel like I would not be able to identify any of the tubes, in a blind test.
Am I alone ?
Do I need to get my hearing checked? LOL!
I was expecting a much different result to be honest.
Im wondering if that because I play and prefer a distorted sound, that the effects of different tubes, has a much less noticeable effect, as opposed to a very clean tone.
Im now considering re-doing the test, utilizing the same 2 amps, but using a much less distorted and more clean setting.
But my thought is that if I seldom play with a clean tone, what would be the point.
Old tubes included several old Bugle Boys, RCA, Zenith, International and Mullard.
New tubes included Mullard, Tungsol, EH, 7025 prefered, Shuguang, Mesa, Marshall red labeled,Marshall white labeled and JJ.
Some have long plates, and some have short.
Dates range from the 1960's used tubes, to modern tubes purchased only a few weeks ago.
I should also add, that both amps are in great order...
No bad power tubes.
And that all tubes sounded great....Just not THAT different
The good news, is that this test re-confirms my own personal lack of needing more tubes!
But....
Im wondering what other MFR's thoughts are, on tube rolling with a high gain, distorted sound ?
Do you feel like more distortion and a higher gain setting, has a lesser effect tube rolling has?
Are you able to identify your favorite tube, in a blind test, at reasonably distorted / high gain levels?
Your thoughts please...
