    These made my old late-60’s Super Reverb sound great again

    Color: Matched Pair
    I put these in a late-60’s Fender Super Reverb that was sorely overdue for new power tubes. Immediately upon firing the amp up with the new tubes installed, I was rewarded with the sonic reminder of just how fantastic this amp sounds.

    I think these came from an outfit called “Apex,” or something like that. I have to say that these two tubes are matched really close to each other because I had my Bias King installed inline. They might just be the closest matched pair that I’ve owned to date.

    Some folks peg the sonics of the JJ 6L6 as being a little flat or 2D or something, but I honestly don’t know what they are talking about. I’ve had some great tubes in this old Super Reverb, and the JJs sound every bit as good. I’ve also owned a bunch of other types of JJ power tubes and can say that they’ve all been both reliable and durable.

    Prior to installing these I had a quad set of grade 4 groove tube 6L6 tubes in my amp with 4 tungsol 12ax7 preamp tubes. I have a Peavey JSX 120 watt head. It was a signature Joe Satriani amp. Comparing these to what I had… These have better mids and low mids. And the gain! Oh damn the gain got tighter… And smoother. The amp gained thickness… Honestly I used to have to always have the trebs up to around 8, mids around 6 and the lows maxed to get the tone i liked. The highs are similar, I did not notice a huge difference. But it did create a much bigger thicker tone. I was able to back off a bit on the lows and the mids are just rich/better. I would definitely recommend these if you have gain that is broken up or just not as smooth as you’d prefer.

    These are wonderful general-purpose valves!

    Color: Matched QuadVerified Purchase
    I have been running these for 8 months, gigging almost weekly. They are installed in a Peavey XXX head driving a 4-ohm 4×12 cabinet.

    These valves are excellent. The sound is supremely transparent, allowing the effects and techniques to come through clearly. Pushed hard, they aren’t prone to unpleasant break-up. They do not appear to be prone to noise pickup via RF or microphonics.

    They have the longevity that astounds me for a glass envelope valve. As I approach the one year mark, I will pick up another set of these just to have on hand.

    Sound good – properly matched. Good product.

    Color: Matched Pair
    Most importantly – the stated values match what I tested. Great work there. The tubes work perfectly in my vintage Bandmaster. They came in great condition and packed carefully. I won’t compare these to other tubes, as sound is subjective but as a product, they met all of my expectations.

    Great Price

    Color: Matched Pair
    I replaced the stock 6L6 tubes in my Bugera v55 with these JJ tubes. I also replaced the three preamp tubes with JJs at the same time. Like others have mentioned, these are at least in my amp brighter and chimney, but for me in a good way.

    I Will see if the sound changes as the tubes Break in. So far I am very happy with the sound.
