Vox VE-PB Valvenergy Power Burst NuTube Boost Pedal
The Valvenergy Power Burst is a booster built around Nutube. One knob and one mini switch is the whole interface, but because the boost runs through a modern vacuum tube design it adds natural compression and saturation rather than simply making things louder.
- Nutube inside: a modern approach to vacuum tube design, for authentic tube-like sound.
- BOOST knob: sets the boost level, and turning it right brings in the Nutube's saturation and compression.
- TREBLE mode: boosts high frequencies, for bringing out the treble.
- NATURAL mode: a clean, tube-like sound, and the standard setting.
- MIDDLE mode: enhances the mid-range, useful for a fuller sound or for soloing.
- Etched chassis: a design that reflects the sound it produces.
The Valvenergy Power Burst brings a new dimension to guitar sound enhancement. It is a simple pedal on the surface, one knob and a mini switch, but incorporating Nutube gives it a way of boosting that a purely solid-state circuit does not have.
Nutube for authentic tube-like sound
At the core of the Power Burst is Nutube, a modern approach to vacuum tube design. That means the pedal does not only boost volume. It also enriches the sound with natural compression and saturation, in the way traditional tube amps do.
Powerful simplicity
The layout is straightforward. A single BOOST knob controls the boost level, and turning it to the right introduces the Nutube's characteristic vacuum tube saturation and compression, adding texture to the signal. A mini switch selects between three distinct sound modes.
Three modes
TREBLE mode boosts high frequencies and is the one to reach for when you want the treble to come forward. NATURAL mode provides a clean, tube-like sound and serves as the standard mode. MIDDLE mode enhances the mid-range, which suits a fuller sound or a solo that needs to sit above the band.
Function meets design
The chassis carries an etched design that reflects the sound it produces, which gives the pedal a distinct look on a crowded board.
Versatile performance
The Power Burst is more than a volume enhancer. It works as a tool for expressive sound shaping, whether you are playing blues and leaning on bending and vibrato, or driving your amp for a classic rock sound. In both cases it responds with rich sustain and clarity.
