Svetlana EL34 vs JJ EL34 II. Both Tube sets came from the tube store and are matched sets to each other so am able to swap in and out without having to touch the bias. Guitar used was 1970 Gibson SG with T-Tops and Amp is a Dr Dan 1968 JMP 50 watt head. Amp and guitar settings never changed. My personal opinion as originally had original JJ EL34s in the amp and wasn't fully happy with them as found the sound to loose. Went to the new JJ II's by recommendation of my amp tech and found them to be much better and tighter sounding tubes over the originals. Used them for awhile and decided to try something different for fun to see what that might do and tried some Svetlana's. Have had them in for a few months now and played a few shows and was fairly happy with them. Since both are matching specs sets from the tube store decided after I now had time to really give them each a good go would swap them back and forth to see which I now preferred more. Of course you won't get the full affect in this video and my camera ain't the best for recording so harder to tell but I find the the JJ II's to be a little more over all balanced, a smoother tube and not quite as harsh on the ears in the high end. The Svetlana's compress and crunch just slightly more at the same settings but again I find the JJ 2's to be more pleasant on the ears. See what you think.
