      GT-EL84-R Duet
      Russia EL84, Good quality, long lasting type with a slightly aggressive edge when pushed into overdrive.
      Most common low power pentode, popularized in early Vox AC30 amps. Rediscovered by Matchless amps and now currently used by nearly every tube amp company. Quick, soft overdrive distortion, great for recording but usually too low volume for live gigs.

      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. High-rated tubes have the most dynamic range and the most clean power/less break-up for power players, jazz guitarists and bass amps.

      Country of origin: Russia

      Great Tubes Once Broken-In

            Comments about Groove Tubes Gold Series GT-EL84-R Matched Power Tubes:

            Groove Tubes' hardness rating (low-medium-high) is very useful. I used the High Rated (mine were 9s) to get added clean headroom from a Vox-type amp that biases output tubes pretty high (near Class-A). The lower-rated GT tubes will distort earlier. One thing though, you have to run these tubes for a while to break them in. Note that these tubes are tested, rated and re-branded Russian tubes (Electron-Harmonix or Sovteks).

            Disappointed

            By Julio-Ie9hM

            from Valparaiso, Chile

            Comments about Groove Tubes Gold Series GT-EL84-R Matched Power Tubes:

            Most of people write a review when they change their old tubes by new ones, so normally the new ones sound much better than the old ones. I decided to change my new Ruby EL84 by matched GT Rate 8, and I must say that I am very disappointed. The fact that GT do not even bother in covering the original Sovtek EL84 6BQ5 brand in it was not enough to bring my expectations down (they are cheaper, BTW). The problem was when I heard them. I recorded a loop in a pedal, so I could hear exactly the same playing with both set of tubes through my guitar amp. The result: Ruby tubes sounded much powerful and fuller that Groove (Sovtek) tubes. The sound lacked of low and high ends. I expected much more from them. I do not recommend them.
