Bugera 12AU7 preamp tube

12AU7

Bugera premium-grade 12AU7 tubes are hand-selected for their expressive tonal range, reliability and ultra-low noise operation – and are highly recommended for all guitar, bass and other audio tube amplifier applications.

Glorious Tone and Dependability

Our 12AU7 high-end preamp tube features ultra-low audio and microphonic noise, and provides the maximum level of gain and overall tonal quality. The 12AU7 is a classic preamp tube found in many vintage and current amps, specifically in phase-splitter or driver stages. The Bugera 12AU7 provides high levels of gain and low output impedance, with superior reliability and consistency and also features an extremely open and expressive tonal spectrum, with a balanced and smooth frequency response. It is simply one of the best 12AU7 tubes ever produced.

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!
