Quality Would you consider this product to be made well? How dependable? Looks well constructed to me. General Your general opinion of this product. My amp is a VibroChamp XD. The stock preamp tube was a Fender (SovTek 12AX7WC). I replaced it with the Svetlana, which doesn't break up as early and gives me more headroom. It still breaks up, but just later. In between, it gives me lots of subtle tones - more harmonics and more musical. It also gave me more gain, and as a result, more volume on the quieter amp models - IE: The Black Face channel 4 - my favorite. And because of the increased gain, it also brings the 6v6 power tube more into play. Which I like. All in all, it was a few bucks well spent. I have about 60 hours on it now, and it seems to keep getting better as it settles in. Tone Bright and snappy? Dark and smooth? Were the pickups hot, mellow, thick, thin? This tube has noticeably more tone than some of the other more linear sounding tubes. No quite a TungSol, and certainly not a Gold Lion, but pleasantly in the middle. If you want early break up and low power distortion, try something else. If you are looking for something with headroom, definition and musical overtones, you might want to give this a try. I'm glad I did.
so sweet!

Quality Would you consider this product to be made well? How dependable? i ordered 2qty svetlana and 2qty ehx 12ax7 tubes for a retube of my jcm2000 dsl 50 head (1998/drak transformers). the svetlana and ehx look identical! the internal structure, silver glaze, and even the glass tip/drop are the same between the two brands. but there definitely is a difference in the sound! Reliability How has it stood up over time? i've had ehx 12ax7 tubes for (5-7) years without any perceived loss in tone. i think i've only blown 1 out of something like 15 that i have in several amps in my collection. i know that new sensor is the parent brand of ehx and svetlana, so i wanted to see what the svetlana was all about. General Your general opinion of this product. looks good. sounds good. i'm diggin' it! Playability and Feel How does it feel, Heavy, Fast, Chunky? How was the neck? Are the controls easy to get to while playing? n/a Tone Bright and snappy? Dark and smooth? Were the pickups hot, mellow, thick, thin? compared to the ehx 12ax7, which these look identical to, the svetlana is a well balanced, even sounding tube. i find the ehx to have a high output, slightly grainy/crunchy distortion character, with a slightly darker syrupy feel than other tubes (jj,tung sol, shung, ei) in the v1 location. the svetlana sounds to be less grainy, more even toned, and smoother than the ehx, while retaining that slightly darker/syrupy response. i've run just about every combination of the most popular 12ax7's in marshall heads, and i always come back to the ehx for the v1 and phase inverter positions. usually i have jj's/ruby's in the other positions, but i'm liking the svetlana's more in v2 and v3, as they are keeping my marshall darker, and more vintage sounding. i always felt like jj's/ruby's were adding too much highs into the signal. i think i've found my winning combination. remember kids...with a darker voiced tube/amp, you can drive the mid control higher for that classic marshall grind.

Great tube- not many places carry it!

Quality Would you consider this product to be made well? How dependable? Haven't had it long enough to rate. Reliability How has it stood up over time? N/A General Your general opinion of this product. I own just about every new production 12ax7 (and a couple nos). I had it narrowed to the EH and Tung Sol being my favorites. I read somewhere if you liked those two to give the Svetlana a shot. I did and was very impressed with it's overall tonal characteristics... A new favorite! Try it yourself. You can't go wrong at this price. A great buy for a great tube. Playability and Feel How does it feel, Heavy, Fast, Chunky? How was the neck? Are the controls easy to get to while playing?
