Vox VX50AG Hybrid Acoustic Guitar Amplifier

The VX Series expands with a new 50W acoustic guitar amplifier that combines portability, power, and authentic tube warmth. Equipped with Nutube vacuum tube technology, this compact amp delivers an uncolored, transparent, and natural sound—faithfully reproducing everything from delicate nuances to bold, dynamic strumming. With a built-in microphone input, it’s an ideal all-in-one solution for live performances, rehearsals, and on-stage monitoring. Its organic, earth-toned color scheme adds a distinctive and refined visual appeal.

Despite its impressive 50W output, the amp weighs just 4.1 kg (9 lbs) and features a compact form factor for effortless transport. A one-piece ABS chassis ensures durability and excellent acoustic performance while keeping weight to a minimum.

Nutube technology makes it possible to achieve high output power in a smaller, more energy-efficient design. The result is the rich harmonic content, natural compression, and sonic depth of a traditional vacuum tube, paired with modern clarity and reliability.

Sound is delivered through a two-way coaxial speaker system, combining a powerful 8-inch speaker with an integrated tweeter. This design produces a full, balanced frequency range—from warm lows to crisp, detailed highs—while providing excellent sound dispersion and precise spatial imaging. The amp responds beautifully to the subtle dynamics and expressive playing techniques unique to acoustic guitar.

A proprietary, optimized bass reflex cabinet has been carefully tuned specifically for acoustic instruments. The lightweight ABS polymer enclosure offers durability and superior acoustic properties, enabling a three-dimensional cabinet design that would be impossible with wood alone. A wooden baffle is incorporated to achieve optimal resonance, while the stone-textured exterior conveys a premium, high-quality feel.

The INSTRUMENT channel features a full three-band EQ (Bass, Middle, Treble), allowing precise tonal shaping across the acoustic guitar’s entire range. The MIC channel includes an independent two-band EQ (Bass and Treble). Each channel is equipped with dedicated effects: chorus, reverb, or chorus+reverb for the instrument channel, and reverb for the mic channel—making it easy to craft polished guitar and vocal tones from a single unit. A built-in power amp limiter ensures clean, undistorted sound even at higher volume levels.

Connectivity is comprehensive and performance-ready. The amp includes INSTRUMENT and MIC inputs, each with its own volume control, and the MIC input supplies +15V phantom power for condenser microphones. A PHASE switch on the instrument input helps reduce acoustic feedback. Additional connections include an AUX IN for backing tracks or rhythm machines, a LINE OUT for direct connection to a PA system, and a PHONES output for silent practice.
