By using VET (Virtual Element Technology), which is based on an analysis of the components and amp circuits themselves, VTX amplifiers produce the most accurate and realistic amplifier sounds to date. - These new amplifiers also feature a multi-stage Valvetronix tube preamp. This preamp design incorporates authentic analog circuitry to achieve the subtle tonal adjustments and capture the nuances that are distinctive of vacuum tube amps. In addition to this clever circuitry, VTX amplifiers feature a tightly sealed cabinet and a proprietary bass-reflex designed to deliver stunning resonance. Go beyond the realm of previous modeling amps with the new VOX Tone Room editing software that lets you customize the existing amps and effects yourself, or create your own! The VTX Series represents an evolutionary step in VOXs Valvetronix Series. These amps combine all-new sophisticated modeling technology with a multi-stage tube pre-amp circuit reproduce the unique distortion, touch sensitivity, and the response that is characteristic of classic tube amps. The new modeling algorithm actually recreates the analog circuits of the most coveted tube amplifiers and allows users to adjust the gain structure, switch between Class A and Class AB operation, and adjust the bias of the amplifier in real time. VTX amplifiers also offer 13 classic effects based on some of the most iconic stompboxes of all time that sound incredible when paired with any of the 11 realistic amplifier models. Additional features like the a tightly sealed cabinet, proprietary bass-reflex design, a USB port, built-in tuner, AUX in jack, and headphone jack make the VTX the best-sounding and most flexible Valvetronix amplifier yet!
