I bough about 6 tubes for my two tube pedals and one mic preamp. Compared to the others (the six new tubes + the three stock ones), this one's output is really weak, it's gain is soft, compared to the others. I don't know whether this is how it is supposed to work, or it happened I received a faulty one, just it does not behaves as the advertised JJ - "high gain".
Other than that, its sound is good, clear and smooth, no emphasis on narrow bandwidths. I am currently using it on my tube mic preamp, which is a loud device, this valve tames is a bit and I see this JJ well fit for this purpose.
As a minus with the service, all the tubes in the package were just thrown in, and their boxes were found smashed on arrival. The tubes inside were intact, though, I could find no noticeable defects.
I have put these in my Line6 DT50 to reduce noise from the cheap tubes. It makes a HECK of a difference. My amp now sounds like it should and I was worried that these were too cheap. I was wrong! No need to go NOS or more expensive, these JJs do the trick just fine. I'm going to get some more to put in my other tube amp and also to keep as backup. At this price, I can sort out my amp collection without breaking the bank. I'm very happy about that.
They come well-packed, brand new and were a breeze to fit. No tube wiggling, they just went straight in. Get these!
