Have you ever noticed how sometimes your rig seems to sound worse or better than usual? The problem with analog audio equipment is that to function, it needs to be powered by a constantly fluctuating electrical source. Power providers deliver an electrical current that oscillates by plus or minus 5 to 10 volts continuously. The result? Your amp and all your gear never sound the same. The solution? The BrownBox 120, which allows you to correct these fluctuations on the fly with your 110/120V amp.
The BrownBox 120 is an absolutely essential tool for anyone using a tube amp. This small box, which you plug between your power outlet and your favorite amp, allows you to adjust the voltage of the current going to your amplifier. With the BrownBox, you get the best possible sound, making your tubes work as they should and at the ideal voltage, ensuring consistent tone every time, whether at home, in the studio, or on stage.
- Voltage attenuator 110-120V AC, 50/60Hz, 5A, delivering up to 540W. Designed for small, medium and large 110/120V amplifiers (e.g., Fender Deluxe/Bassman/Twin, Marshall 50W/100W, Vox AC30), it can also be used for parallel or dual amp setups.
- Easy-to-read backlit LCD screen allowing real-time monitoring of voltage and amperage, also useful for diagnostics.
