Groove Tubes

collapse expand iconDescription

The Groove Tubes GT-12AT7 preamp tube is designed for outstanding and consistent performance when mixing and matching in order to get a signature tone from your amp. Made with a durable design that can be used as a phase splitter or driver tube, the 12AT7 is ideal for use in vibrato or reverb circuits where consistent, high-output power is desired. It can also sub for a 12AX7 to lower gain and produce a slightly warmer tone.

    Ok this 6505+ head is out of control Uber metal. So I put this in the shared tube socket V1, now get just a bit of breakup on clean at 50%, And a nice useable fusion tone at lead 100%. Remember speaker choice is key too.💕🎶🎸

    It seems like the previous reviewer did not understand the use of the AT7 tube. It is used in the reverb channel or more importantly in the phase inverter position (the tube before the first power tube). The GT website even states this. It is primarily a functional tube (above) and not a tone tube to be used in V1 of V2. It is roughly 80% the power of an AX7. This tube does contribute more to feel than tone and is brighter and more pick sensitive when used as a PI. You can increase the Master volume and use it to overdrive the power tubes. I'm not a fan of GT but this is one of their best tested Russian tubes (still used as military standard) and durable tubes made to last. So use it correctly and you will get a softer, more articulated playing amp!

  • Terrible. Do not buy these.

    I was persuaded into buying these tubes instead of waiting for the JJ tubes I should've waited for. They sound so overly-mellow and flat with no punch. They are not bright like the salesman told me, and you can barely hear the high end in chords. Playing the higher strings is the worst, as they sound bare and empty. Not to mention that everywhere you read about Groove Tubes, it says they're just re-packaged and re-labeled (sometimes cheaper) tubes from other brands. Save yourself the stress and money... don't buy these.
