    Best I've used

    I'm playing Les Pauls & Explorers through a Marshall half-stack. My last 12ax7 was a Tungsol, I liked it for hard rock and metal but that was the extent of its capability. The groove tube is capable of hard rock and metal and so much more, my amp is much more versatile now.
    I doubt I'll try any other pre-amp tubes from now on.

    Warm sounding high gain tube

    I use this in a VOX VT20+. It has a 1 watt tube power amp that's fed into a discreet SS power amp. It gives you valve characteristics in the power section, which is nice, but the stock Ruby was a bit too open for my liking. This has as much gain, but isn't as open on the top end to make the sound a bit warmer. The difference is subtle, but I like it better.

    Excellent warmth and gain, but has a tendency to be faulty

    For the price its hard to beat the sound that these 12ax7s make. Warm, clear, and drives super hard and musically at high volume. The biggest caveat is they are amazing tubes when you can get your hands on a set that actually work. I love their sound, but hate that if I buy 5 of them, at least 2 will come with either heavy microphonics or corroded pins right out of the box. With mass production and engineering advances we have created brilliant new sounds and music technology, but at the expense that there are so many more lemons on the market than there ever have been.
