The Groove Tubes GT-EL34-M is a new version of the iconic EL34s used in both the audio world and guitar amp world. This tube was introduced at the January 2005 NAMM trade show in Anaheim, California, and it started to attract attention. It's a faithful reproduction of the classic Mullard EL34, known worldwide as the "holy grail" of power tubes for high gain guitar amplifiers.
The GT-EL34-M is a pentode power vacuum tube designed as a replacement for aging tubes in high gain amplifiers, such as Marshalls. Any amp using EL34 power tubes should benefit from the excellent sounding, highly responsive, and harmonically rich tone produced by these tubes. The original Mullard EL34, which was the factory tube in Marshall amps, has been out of production since the early 1970s, and it not unusual to see these rare and highly sought after tubes being sold for hundreds of dollars each. Groove Tubes went down to the finest detail of the mica material, its nickel plated base, and finned grids to create the most authentic and classic EL34 power tube that's been produced in the last three decades. Its tone is unmistakable; big fat tone with well defined chords and single notes. It isn't mushy when pushed to distortion, and it really makes the reissue amps wake up and sound like vintage amps.
So look no farther, if you're in need of some replacements for those classic Mullards, or you just want to save them for a rainy day. We offer the GT-EL34-M as a single tube and in matched sets of two or four tubes, for optimum performance. We know that matched tube sets dramatically improve sustain by eliminating phase cancellation, which occurs when dissimilar tones coming from unmatched tubes are combined and cancel out certain frequencies. You will also have improved harmonic balance, meaning all the notes you play will have the same amplitude. No weak or dull spots in your tone. You will also have longer life from your amp, since balanced tube sets reduce stress that occurs when a stronger tube has to work harder to make up for the weaker. Your output transformer will actually run cooler, because matched tube sets drive the output transformer evenly, and that's a good thing for a classic amp.
