Quality is Always #1
Our state-of-the-art process begins with selecting only the finest tubes from all over the world. We then subject them to the most rigorous testing procedures, which are conducted in demanding “real-world” applications. Only about 10% pass the test and are given the BUGERA name and stamp of approval. The rest are recycled responsibly.
This highly labor-intensive process is an art we’ve mastered over many years. As a result, ours are the finest and most musical tubes you can buy – at any price!
