Our obsession starts with tubes and ends with one of the most rigorous testing programs of any amplifier manufacturer. Literally every fourth technician in the BUGERA factory is a Quality Control Inspector. Every head and combo undergoes a battery of tests at each stage of assembly. Finally, each amp is burned in, calibrated and tested by a guitarist. Yes, a highly skilled guitarist actually plays through every single amp. Then, and only then, do they earn the name BUGERA. All of these advanced manufacturing methods, old school design and loving care that goes into building BUGERA, means you get a rock-solid amp that can take years of hard use. Just ask our endorsers who have racked up thousands of gigs in the last year alone.
