Premium quality EL-34 with nice harmonic reach, layering, complexity, fullness, and richness.
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’s Badlander and Triple Crown EL-based models, as well as great alternate power tubes in MESA’s Mark and Rectifier lines.
