Mesa/Boogie 5AR4/GZ34 Rectifier Tube

Dial in just the right amount of sag with the 5AR4/GZ34 rectifier tube. Designed to be Mesa's least "saggy" tube, this model adds character to your sound.

The Mesa 5AR4 rectifier tube produces a vintage feel with light to mild "sag". While it produces more "sag" than Silicon Diodes, it is the least "saggy" of Mesa's tube rectifier offerings. Used in vintage Mesa amps like the Heartbreaker, Blue Angel and Maverick as well as many other vintage, non-Mesa amplifiers.

Mesa Rectifier Tubes are premium grade and offer unsurpassed consistency and reliability for ANY tube amplifier.
