Based on a tube which is considered an icon to EL34 users in both the audio world and guitar amp world, the GT-EL34M Power Tubes Quartet provides classic tonality. The original was a classic, and now the GT-EL34M is on its way to developing its own great track record just as the GT-6L6GE, E34LS, and KT88SV proprietary tubes have. This is the matched pair version, its also available in matched quads.

Great Tubes!

I had never switched out the Tubes in my Marshall amp until one of them finally went. sweetwater was a huge help in letting me know exactly what tubes would sound and work best. My sound got so much better when I put these GT's in!

Great Tubes

I play through a pair of Marshall JCM900 amps in stereo. I use a high gain heavy sound. I've tried various tubes and still come back to these. I haven't found anything that sounds as good for what I do as the GT EL-34. As with any tube, make sure they are biased correctly or they won't last as long as they should. And for anyone considering JJ tubes, don't even think about it. For my situation, that was the worse possible tube I've ever heard. JJ tubes sounded like worn out GTs. At first I thought I had a bad set and tried another set, same thing.

Groovy

Changed out old and put new in. Tight and clean. High gain holds well.
Music background: Wanna be guitarist.

Not So Good

Yes, beware the retail packaging. The GT box allows the tubes to rattle around against each other during shipping. There is no protection. I am surprised they made it intact after the 1000 mile plus journey to me. They work, but the sound is just so so. I tried a new pair of JJ E34L tubes and the JJ's are much sweeter sounding.The GTs EL34Ms are Chinese made and I would not recommend them.
