I am a bass player and its hard to decide on which tube to choose when you buy your first tube amp. I have had this amp 4 yrs and never needed a tube until now. I originally purchased a tube of another brand and chose solely on the reviews and ratings and cost a few dollars more. It took away all the characteristics that made my favorite amp what it is. So I blindly bought these JJ tubes on the advice of a friend and I am completely happy. Owners manual called for a Groove Tube but I wanted something else and a Mesa tube was in my amp but I wanted to order from MF and I didnt see any Mesa tubes here. I am very happy!

My low ends are back!! My lo mids are back and my attack is all there again. I love the way the gain can make the sound flow or growl. I have a hot set up in my bass and the other tube I put in, it took all of what I loved about bass amp away. It took out all my lower freqs. And my tone was tinnier with a slight ring to it. But after some major eq tweeks I was able to get it almost acceptable. But this JJ tube brought my eq settings back into the ballpark and gave me more of what I have been missing for a couple years now.

As we all know, different tubes sound good in different amps. I would just personally not recommend this tube for a Mesa Dual Rec. I changed out all my preamp tubes with the jj's and it made the amp sound extremely noisy, fizzy and thin. I switched back to some mesa tubes and problem solved. Maybe I just got a bad set or something because jj's are supposed to be pretty good from what I hear. Also, Musiciansfriend really needs to change how they ship tubes. One of the tubes came to me already broken.

      My favorite 12AX7. I have these in all my amps and tube preamps. I'm using these in my 94 Blues Deville and my 78 Music Man 212-65.

      Comments about JJ Electronics 12AX7 / ECC83 Preamp Vacuum Tube:

      Replaced the stock tubes on my Marshall DSL 40C with these and the excessive noise that has been there since day gone! This was my first tube amp so I was not really sure if the noise was normal. This was actually my second one because I re[placed the first one thinking it was defective. One other difference between the JJ's and stock tubes was a slightly cleaner sound with more volume. My amp is now quieter at full volume than it was with the volume on 2!

            Haven't used much yet but seems to have a little less gain than the tube it replaced, I may try a different tube soon for additional comparison but it works well enough.

                    I have used these before in a Fender Blues Jr. This time in a Tubemeister 18. These are excellent preamp tubes! Warm up the sound and take that pristine sharp edge off. Actually cut back the mids a tad after installation. I use and appreciate a good clean sound and these are the ticket.
