Groove Tubes Gold Series GT-6L6-S Matched Power Tubes Medium (4-7 GT Rating) Duet guitar amp tubes are Slovakian-made with high power and very aggressive dynamic tone...punchy, but still sweet. New GT design with more power and heavy duty components. High power type with more highs and lows than other 6L6 types.

Country of origin: Slovakia

Low-rated tubes have early break-up and distortion, wide range and softer attack good for rock and blues solos. Medium-rated tubes offer normal performance, great dynamic range/attack and are the best all around rating type for all styles of playing.

  • Great for twin reverb

    As reviewed by TwinJunkie on 1/13/2011

    I have these in my twin reverb RI and am in love with these tubes. If you want that cranked twin overdrive tone at lower volumes you will LOVE these tubes! A bit pricey but worth it in my opinion. If your looking for crystal clear cleans these aren't for you. A strat and these 6L6S tubes are heaven to me. PERIOD!!

  • These are JJ/Teslas

    As reviewed by Jimbo on 6/21/2007

    These are GT's rebranded JJ power tubes. I use JJs in my Fender DeVille and love the clarity and musicalness of the tubes. These are top-notch tubes. That said, GT has really marked up the tubes just to carry the GT label. I'd look for regular JJ brand, which should cost around $30 a matched pair.
