The BUGERA 5881 is all about classic American tube tone. It has an emphasis on power, durability, consistency and high power handling capability. With its beautifully deep bass, articulate mids and tapered highs, the 5881 lends itself to styles such as blues, jazz, fusion and R&B where a rich and warm tone is desired. If you find your amp too bright sounding with standard 5881s, the BUGERA 5881 may be your tone solution.
Our state-of-the-art process starts by testing only the finest tubes available from all over the world. We test and stress each tube under the toughest "real-world" conditions and measure them by applying the tightest and most demanding specifications. This highly labor-intensive process cannot be substituted by machines and selecting/matching tubes is an art which we mastered over many years.
A full set of 4 hand-selected and matched premium-grade 5881 power tubes, the BUGERA 5881-4 will bring out the best in your amplifier. Their consistently robust power, rugged durability and high-voltage performance make them ideal for all guitar, bass and other audio tube amplifier applications.
