Mesa Boogie 750541F Rectifier Tube - 5U4GB

Available at Sadek Music, the Mesa 5U4GB tube can be found in all the latest Mesa/Boogie tube amplifiers. Dubbed the company’s “factory favorite,” it’s easy to see why. The MESA 5U4GB is based on classic 1950s tube technology and represents an improved version of the original 5U4 design. It offers enhanced reliability while being more compact—roughly the size of a 6L6 power tube—so be mindful of positioning it inside your amplifier. This tube delivers a traditional vintage sag with an elastic, compressed feel, giving your tone that classic, expressive response. The MESA 5U4GB is a must-have for players seeking that iconic Mesa/Boogie vibe.
