      If you're a NOS tube snob that does'nt mind spending ridiculous amounts of cash so you can say you have NOS tubes, you're gonna hate these. But if you're looking for an excellent current production preamp tube and want great tone and awesome gain, you can't go wrong with these. I play Hard rock, metal and "shred" style music.

      I have 4 of these Tung-Sol's in my Peavey 6505 plus (V1 and gain stages) replacing the JJ's that were in it and was immediately greeted with improved gain, punch and BIG tone. We all hear tone differently and to me, these are one of the best current production tubes out there if not THE best in this price range. I had gotten used to the tone and gain of the JJ's and did'nt realize how weak and anemic sounding they were. After I played the Tung-Sols for about a week, I put the JJ's back in just to satisy my curiosity and MAN are they weak. Keeping them for backup though because I'm waiting to see about the reliability of these Tung-Sols. I hope they last because the tone and gain RULES!

      I tried one in just the V1 and was happy with the improvement. After that, I put in 3 more in the gain stages and tone stack (my Phase inverter and effects loop tubes are balanced Pentas) and was blown away by them. But as the saying goes, to each his own.

      I bought eight tubes from MF... out of the four Tung-Sol 12AX7's I ordered, three of the four tested below 40/120, dead-out-of-the-box. Poor, poor, poor quality. When I called to return them, the woman who initially handled the call told me that 'tubes are not returnable if the box has been opened', which is not MF policy. Poor, poor, poor service. It's been seven days since MF confirmed receiving the return, and I still don't have my refund. Poor, poor, poor policy. I bought eight tubes from MF... and only ONE was usable. I also order a matched quartet of Tung-Sol 6L6's... one of the four arrived CRACKED, and the silver coating inside the tube was white, flakey, and burned off. I never used nor even tested this tube, so it was obvious the damage did not occur in shipping, but must have occurred while the set was being tested/matched. Poor, poor, poor.
      I will NEVER, repeat NEVER order tubes from Musicians Friend ever again.

          I really like these tubes in my Orange Rockerverb 100 MkII. They have a little less gain than what came in the amp but is of no consequence because the amp still has an enormous amount of gain. I like the tone much better. It is less biting and much smoother.

            Comments about Tung-Sol 12AX7 Tube:

            Got this because I heard that Peavey Classic 30's did well with one of these in preamp V1 position. The preamp had JJ's in 1 and 2 and a Ruby in V3. To me the JJ sounded better in V1, so I put this in V3 and noticed a pleasant change vs the Ruby. The Tung Sol seems more hi fi, with better bass and more extended highs. I realize that is subjective, but I'm happier with my clean sound and my amp settings.

              Comments about Tung-Sol 12AX7 Tube:

              I've heard that these preamp tubes last about twice as long as the power tubes - I got about 500 hours out of my power tube before it started going out (making random noises). So that's about a year for my power tube - to make life easy, I change both the preamp and power tube at the same time. I use it in a VHT Special 6 (one preamp and one power tube), so for me changing the tubes once a year just before our church Christmas program is easy to keep track of.

              The sound of this brand was better (in my mind) than the stock tube. I did play with a 5157 preamp tube but it didn't give me enough clean head room. And the distortion the 5157 gave me wasn't the greatest either.

                      I put these in my '59 Bassman after hearing all the hype. I didn't notice a major difference in tone from the EH's I've been using for years, but they sounded good. I do a lot of festivals and other outdoor gigs where the 110v power supplied to our gear is sometimes less than clean. Pretty common for a gigging pro. After six months I had one working, one noisy as heck and one that was stone dead. Might just be my bad luck, but I've had better durability from Chinese tubes, and the Tung Sol's did not produce a noticeable improvement in sound over the EH's, which I've gone back to using.

                                I like this tube. Despite the fact that it's made by sovtek. This little guy works great in newer amps that have cascading gain stages and is nice and quiet. MF decided to let it roll around in the box with a couple of speakers though so watch what you order it with! Overall, pretty decent tone in a modern tube.

                                    These tubes replaced stock in a Fender Excelsior and an old Super Champ XD, together with Tung-sol 6V6GTs. What a difference! Warmth, smooth break-up, powerful yet clearly articulated bass notes, bell-like trebles, low noise and no pops. What more could you ask for?

                                        I have used these preamp tubes in many amps. Best suited for V1 position. They are on the bright side, but not harsh. Tight and punchy bass. Sound great in clean amps (Fender Twin, Blues Jr, etc).

                                        These can brighten up a darker amp and tighten the low end in high gain amps. Low microphonics with plenty of gain

                                        PLEASE NOTE: Do not use these in Cathode Follower Positions in your amp. If you don't know, look it up. The tubes wont last long in those positions.
