The Mesa Boogie 5AR4 Rectifier Tube is a gas‑filled rectifier designed as a perfect replacement for guitar amplifiers. Known for producing more tube sag than silicon diodes, the 5AR4 (also referred to as GZ34) delivers a highly responsive, dynamic tone with rich vintage character. It is used in models such as the Mesa Boogie Heartbreaker, Blue Angel, and Maverick, and serves as an ideal replacement for many other classic amps.
