The MESA EL-34 STR 446 is a premium quality EL-34 in the classic style and sound. They have nice harmonic reach, layering and complexity in the top end and a bit more fullness mids and richness in the low end when compared to some vintage renderings. With these favorable qualities they are a good choice for most EL-34 based amplifiers and certainly for Mesa/Boogie's Badlander and Triple Crown EL-based models, as well as great alternate power tubes in their Mark and Rectifier lines.

Only the highest quality and most consistent vacuum tubes earn the MESA Engineering seal of approval. All MESA tubes offer unsurpassed consistency and reliability for ANY tube amplifier, and certainly MESA amplifiers!
