That's how a Marshall should sound
Recently replaced some junk tubes (won't mention the brand name, but it starts with an R) that a repair shop slipped in my Marshall JCM2000 100 watt head without even asking me if I wanted them replaced with the like JJ EL34s that were in it. Checked around for pricing on different tubes and came across these. Thought I'd try something different. Have not been disappointed so far. Actually I'm very pleased with how they've brought my head to life. Almost like they've found the best tones out of all of the commonly used tubes you'd find in a Marshall and stuffed them in one tube. Very smooth distortion, bass and highs for days. Don't be thrown off that they come in a slightly smaller envelope than the EL34s. They pack a lot of "heat". I think I've found my go to tubes.
