I put this in V1 of my Blackstar HT Soloist 60. WOW noticed the 3-D sound they were talking about. Lot more headroom and bottom end on the clean channel, the OD had crunch to sweeping gain with a more pronounced EQ and presence response.Going to get a few more for my other amps.The Tung-sol sounded totally different in V1 then the OEM tubes.
I bought this to replace the stock tube in my behringer VT999. The pedal was useless to me and sounded like a bad fuzz pedal with the original tube. Then I installed the Tung-Sol and I must say the difference is huge. Now it sounds great with plenty of usable tones on tap and sounds more like an overdrive pedal should.
One of my favorite current product preamp tubes for my Peavey Classic 30 and Fender Hot Rod Deluxe amps. Great all around tube. Very musical and fat sound, but can get dirty when it needs to. I tend to use it for the V1 and V2 slots in my amp.
Great Gold pin tubes. Puts new life into my amp. Very very fast shipping. Thanks Amplified parts!
Bought a few of these and love them but unfortunately they have developed bad rattle to them. Switched them out with some good ol' JJ 12AX7 and rattle disappeared. Maybe just a couple bad apples in the batch but think I'm going to stick with the JJs.
Installed these tubes in blues jr Iii along with cannibus Rex speaker. It has increased headroom better dynamics and got rid of thin brittle highs. Everyone I play with noticed right away and could not believe the difference. Will do same mods to my USA bjr and run them both with Aby box.been chasing tone for a long time and finally got what I wanted.
I really like these tubes... I like these as a high gain 12AX7.... they are big and loud when played, yet nice and quiet at idle. Comparing a few things, the China 12AX7's have the gain, but with an annoying hiss added.... The JJ short plate is quiet at idle, but not as much gain. If I'm going for strong gain, I pick the TungSol... if I want modest gain, I pick the JJ. I really hate amps that don't shush when they aren't being played...
I replaced my JJ's with these in my Bugera 1960 Infinium and wow what a difference. I also put in tungsol kt66's which i also love. I decided on the full tungsol set after chatting with the online support. I highly recommend these tubes and talking with their support.
I replaced a set of jjs with these in a fender champion 600 (reissue) and man, what a difference! much smoother than jjs. I found the jjs so crunchy that they came off as harsh. the tung-sols are a great alternative that I'm probably going to stick with!
plus amplifiedparts.com has always been great to deal with!
I used the Tungsol to replace the stock GT tubes in the preamp section. What a difference! These are much quieter. I lost the hiss tube noise.The clarity is better and tone more balanced. Not as harsh as the GT's Also not as bright yet still plenty bright. The amp sound much better. Note. I replaced three tubes: the V1 normal, theV2 vibrato and the V4 Reverb recovery/ half gain stage for vibrato channel.
