The Power Burst is the boost pedal from Vox's "Valvenergy" series, featuring a Nutube tube. Featuring a distinctive LED display that shows the signal's response to the effect, it features a single knob and three modes: TREBLE to emphasize high frequencies, NATURAL for a natural response, and MIDDLE to emphasize midrange frequencies. As with all Valvenergy pedals, the Power Burst recreates tube sounds, providing the typical natural compression of a tube amp. Watch Giovanni Buttitta's demo video of Vox's Valvenergy 2 pedals.
