A power tube died in my blues jr and subsequently also made my amp blow a fuse. Once I figured this out, i had to buy some new tubes, and sweet jesus jj delivers! My blues jr is by far my favorite amp, and it's back from the dead.
That said I don't know the tenure of these tubes so I'm hoping they last while, I got about 9 months on the groove tubes so hopefully these will outlast those. They sound more or less like the groove tubes, but I feel like they have slightly more bottom end and gain. I used to have to turn on the "fat" boost to get a good amount of gain from the amp but now with the volume set at 12 I'm pretty happy with it's gain level. The amp is the primary factor in tone, but these tubes get the job done and give the amp the necessarily means to do its job.
At any rate, I'd recommend these. They brought my amp back to life, which thoroughly pleased me, not to mention they sound great and I'm in hog heaven now that my amps back to working...
Purchased a matched pair of JJ EL84's to "upgrade" my Vox AC10C1. The AC10C1 is a new amp, but I've heard that JJ power amp tubes are a great pairing with Vox-style amps, as they help bring out that trademark "chime". The results with the new tubes have been quite good. The amp really sparkles with valve/tube sustain and saturation, and it gets bright without being overly harsh or thin. Even compared to the stock tubes, I feel that the JJ's were an improvement. Installation was a breeze. Would buy these again without a doubt when it comes time to re-tube.
I put these into my Mesa/Boogie 20/20 power amp. My guitar rig was sounding like it lost it edge, grit, etc... whatever you want to call it. Even after I recently replaced the 12ax7's in my preamp. I immediately could here the difference. My rig now has that warm, rich, creamy, singing harmonic response that it was missing. 5 Stars for the performance and sound of the amp with the new tubes. I can only hope the tubes last, which is yet to be seen. But I have confidence as JJ Electronics has a good reputation and I have used their preamp tubes with great success in the past.
