Chinese made copy of the old USA 6V6 we loved in our old Deluxe Reverbs. Round, warm, fat tone with lower power put great for a soft blues tone or great fat classic rock sound too.

4. Groove Tubes Premium EL34 Duet

The Classic pentode power tube used in Marshall, Hiwatt, Laney, and similar Euro type amps. These tubes have a big bottom and a crisp top end that get crunchy when pushed hard. It also has sort of a hollow midrange response. The choice of the modern rockers, ala British Rock & Heavy Metal.

5. Groove Tubes GT-EL34-R Medium Duet Amplifier Tube

Groove Tubes GT-EL34-R Medium Duet Amplifier Tube

The original power platform behind most high-powered British guitar stacks from the ’60s onward. Output is generally between 20 and 25 watts, with pronounced mid-range punch, tight low end and crisp top end that breaks up relatively smoothly and gets a little crunchy when pushed hard. It provides a great voice that stands out in a band mix as the mids tend to power their way through an overall mix. Big brother to the EL84. The GT EL34 is based on the original Mullard EL34 of the '60s. Mullard produced it for about 15 years, and this is a faithful reproduction of the classic XF2 dual-getter version. It has a big, fat and well-defined tone and really "wakes up" reissue amps to perform like the originals. As close as you can get to vintage power tube heaven.

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

8. Groove Tubes GT-EL84-S Quartet Replacement Guitar Tubes

New European version with even more response, higher power and warmer tone. Most common low power pentone, 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.
