Preferred Series 12AX7
From our review: "This 12AX7 is a versatile, quiet tube that will be at home in just about anyone's guitar or HIFI amplifier. In a Fender Champ they displayed no microphonics or rattling, and had a warm, smooth character that can still get rowdy when driven. The detail is all there as well..."
This 12AX7 audio tube has crimped, mid-sized plates, think mica spacers, and a disc-style getter ring.

Great tube!
by Tim -
I tried these because I really liked the 7025.. happy to say these are on par IMO. Probably a touch warmer sounding but I like that! Works well in my Orange's V1 position.
Beautiful in my Fender Blues Junior

I tried these in my blues Junior and I’m blown away by the beautiful difference in sound that I get from these tubes when compared to the stock groove tubes. Beautifully balanced and harmonic. Get these and don’t look back!
