Draw the line at perfection

The Eurovolt is the European 230 volt version of the American 110 volt Brownbox and is used by guitarists and studios all over the world.

Professional recording studios, technicians and musicians agree that the correct supply voltage is essential for optimal tube amp performance. You too can now achieve that elusive, classic warm vintage sound with the Eurovolt.
The foundation for any world-class signature tone naturally starts with talent, but it also requires a consistent and reliable signal chain. The Eurovolt provides that solid basis.
Guitarists who have been using the Eurovolt for a long time notice how tone, touch and feel have finally come together, offering them improved harmonics and dynamic amp performance. Make sure you also get a beautiful basic sound with the Eurovolt. Classic tube sound starts with the Eurovolt.
Known guitarists like Joe Satriani, Orianthi, Sammy Hagar, Peter Stroud (Sheryl Crow), Clay Cook (Zac Brown Band), Charlie Starr (Blackberry Smoke), Jimmy Herring, George Lynch, Roy Jansen (Pilgrims), Derek Trucks, Buddy Miller , Phil Keaggy, Tom Guerra, JD Simo, Eric Ambel (Joan Jett and the Blackhearts, The Dellords, Steve Earle): they all use the Brownbox / Eurovolt.

Why voltage optimization?

Establishes the basis for your signal chain and the starting point in building a consistent signature tone. Earlier power tube saturation equals earlier break-up at more usable volume levels .
2. A smoother tonal shift toward even order harmonics, revealing the amplifier’s true designed tone fundamental .

3. Lower internal voltages = lower dissipation = longer component life.

For decades, engineers and players who understand the fundamentals of tube amps and tone have used voltage optimization as an essential and permanent part of their equipment. They know from experience that their tone and signal chain depend directly on the supply voltage.
The correct supply voltage gives the original sound, which is the beginning and the basis of the signal path. Keep in mind that pedals and attenuators color your sound, they don’t make it. Eurovolt is the first line level regulator designed for tube amp purists who understand where their tone originates.
