Introduction
The VOX MV50-AC-SET is a professional, high-performance hybrid micro guitar amplifier head and speaker cabinet package designed to deliver the legendary, touch-sensitive chime and organic crunch of a traditional VOX AC30 tube stack. Fusing Korg's groundbreaking Nutube preamp technology with an incredibly efficient power stage and a custom-voiced 8-inch cabinet, this ultra-portable mini stack fits beautifully into minimalist desktop recording workspaces and portable live rehearsal rigs, delivering massive, uncompressed tone in a system that weighs under 10 pounds.
Main Features
The defining strength of the VOX MV50-AC-SET lies in its all-analog preamp circuitry, next-generation vacuum tube technology, and perfectly matched cabinet resonance. The heart of the MV50-AC micro-head is a Korg Nutube 6P1 double-triode vacuum tube. This revolutionary component delivers the authentic harmonic warmth, natural compression, and touch-sensitive sag of traditional glass tubes while drawing minimal power and generating negligible heat. Voiced specifically to capture the signature high-end chime, sparkling cleans, and dynamic overdrive of an AC30 combo, the preamp is paired with a highly efficient Class D power amplifier that outputs up to 50 watts of RMS power into a 4-ohm load.
The package includes the custom-designed VOX BC108 Speaker Cabinet, which is engineered specifically to enhance and round out the low-frequency response of the MV50 head. The cabinet features an 8-inch VOX original speaker mounted from the front of the enclosure. This structural design provides a much wider, clearer sound dispersion and a punchier, fuller tone than typical small-format cabinets. The active head also features a 1/4-inch combined Line/Headphone output jack driven by a premium, custom-designed cabinet simulation circuit, allowing you to capture high-definition, mic-cabinet-quality tracks directly into your DAW without using loud physical microphones.
Usage Scenarios
- Studio: Reclaim desktop space and record direct-to-board, high-fidelity AC30 tracks by running the cabinet-simulated line output straight to your audio interface.
- Live performance: Transport an entire 50-watt tube rig in your gig bag, easily driving full-sized 4×12 cabinets at gig-level volumes on stage.
- Practice: Run silent late-night practice sessions using the headphone jack, or jam along to backing tracks using standard wall power.
- Recording: Track responsive, touch-sensitive overdriven rhythms in your home studio, using your guitar's volume knob to clean up the analog tube gain.
- Education: Instruct students on historical English rock tones, demonstrating how cabinet configurations alter low-end resonance using the Flat/Deep EQ switch.

CK Music Staff Recommendation
The CK Music team recommends the VOX MV50-AC-SET for recording guitarists, traveling performers, and home hobbyists who want the genuine touch response, chime, and organic sag of a real VOX AC30 stack but refuse to carry heavy gear. Most micro-amplifiers rely entirely on digital modeling chips that can sound sterile and lack the natural feedback dynamics of a physical tube amp. The VOX MV50-AC completely solves this problem. By combining a real Korg Nutube preamp with a robust Class D power stage and a front-mounted 8-inch speaker cabinet, it successfully projects a rich, full-bodied tone with remarkable low-end definitions. Combined with its medical-grade cabinet-simulated output and a total combined weight of under 10 pounds, it operates as an exceptionally smart, professional-grade desktop recording and live-gigging package.
