MESA/Boogie 5U4GB Rectifier Tube
The MESA/Boogie 5U4GB Rectifier Tube produces a traditional vintage sag with the most elastic and compressed feel of the two 5U4’s that MESA/Boogie offers. Amazing feel and exceptional overall quality make this a factory favorite. Based on classic 1950s technology, the 5U4GB is a vastly improved 5U4 design that is extremely reliable and consistent, as well as more compact compared to original coke bottle 5U4Gs.
