The Rocktron VooDu Valve LTD is a 24-bit DSP professional tube guitar preamp, offering 12 unparalleled effect algorithms and superior sound quality. It features complete programmability and full MIDI implementation, coupled with a user-friendly operating format. Advanced Speaker Simulation provides a realistic approximation of a miked speaker cabinet for direct line-level or headphone listening. Full parametric pre and post EQ grants comprehensive tonal control over each preset. HUSH Noise Reduction ensures quiet operation, eliminating noise during play and providing silence when idle. The "Variac" Simulation adjusts the distortion onset level, offering more gain for high-gain applications and robust cleaner presets. An internal Wah-Wah function allows expression pedal control, obviating the need for external pedals. High-quality digital effects include Reverb, Pitch Shifting, Phasing, Compression, Tremolo, Chorus, Flanging, and Delay. XLR outputs are integrated for direct mixer input, enhancing connectivity options.
