Groove Tubes E34LS Tube Quartet (EL34)

This long-lasting tube boosts your sound giving you maximum tone and power. It's perfect for the modern rock guitarist.

This exclusive GT design features special "heat wings" attached to plate for more power, longer life, and better tone. The 1st choice of Matchless and many pro players including Billy Gibbons, Joe Perry, and Joe Walsh, these tubes are very dynamic, and produce a big bottom. The most powerful in their class.

EL34 Type (typical power ranges from 25 to 38 watts)

This is 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. These are the choice of the modern rockers, a la British Rock and Heavy Metal.

If you have a Matchless-you need these.....
Sound
My Matchless Chief has a new life. The original tubes-which were also Groove Tubes of the same model were spent. Nine years was way too long-I bought the amp on eBay and thought-my VHT blows this away-now with the new tubes-it's the other way around. What tone! These need changing on a yearly basis if you play out or play a lot.
Features
What can you say-it's not about features-it's about tone....

I'm going to put as many miles on these as I can-then buy a new set. I'll save the trouble and buy a new set now.....
