The MESA EL34 STR 447 is our very best overall, premium grade NOS equivalent EL-34 and our tube of choice in the production of all new MESA EL-34 powered models. It offers traditional EL-34 tone & feel – urgent and aggressive – and is an excellent choice for all styles of gain, especially classic rock, alternative rock & metal. This tube is true to it’s British origins with tight, focused low end, crushing midrange crunch and crystal-like highs. It’s one of our favorites for authentic Brit tones.
