JJ preamp tube with low noise and low microphonics. Great for phase inverters, reverb circuits, or any application which calls for 12AT7 tubes.

  • Great preamp tube.

    As reviewed by Christopher on 12/29/2014

    These EH 12AX7s (along with the Tung-Sol) are one of my favorites for small single-preamp-tube amps. Very musical. Can't go wrong.

  • Game changer!

    As reviewed by Michael Taris _ on 1/23/2014

    This little tube brought my Fender Super Sonic 22 back to life. I was noticing my amp just wasn't inspiring me to play, it was just sounding flat almost solid state-ish. I checked all the pre-amp tubes and found the stock 12AT7 a bit noisy when tapping it with a orange-wood stick. Replaced the stock Groove Tube 12AT7 with the JJ 12AT7(ECC81) and my amp sounds better than it ever did. Much more than I expected. I wasn't expecting that much of a tonal improvement. May do a complete JJ re-tube.

  • JnJ tubes

    As reviewed by keith norvell on 5/2/2012

    I recently bought a used Fender Deluxe Reverb with all original tubes. After reading on-line help sites I purchased JnJ tubes including 12ax7s, 12au7, and a 5u4gb rectifier tube. What an improvement!
