Vox Valvenergy Fuel Injector

Vox · pedal

The Vox Valvenergy Fuel Injector is a tube overdrive pedal built around Vox's Nutube technology, a genuine miniature vacuum tube adapted from vacuum fluorescent display components, giving it real tube harmonic character without a traditional tube's heat, bulk, or maintenance needs. It runs on standard 9V power with no separate heater or ventilation required, delivering dynamic, touch-responsive overdrive with the smooth, musical harmonic overtones associated with genuine tube circuits. It's part of Vox's Valvenergy line aimed at bringing authentic tube-driven dynamics into a compact, low-maintenance pedal format.
