Compact and lightweight two-channel 50W combo amplifier for acoustic guitar from VX series that features Nutube, an enhanced vacuum tube designed by KORG. With an uncoloured, honest, and flat sound, it delivers beautifully rich sound that covers everything from detailed nuances to powerful strokes. Since it also provides a mic jack, it can be easily carried to a live event for a complete single-unit setup and it is also useful for on-stage monitoring. By using Nutube, this amp achieves high 50W output power while being more compact, lightweight, and power-efficient. The one-piece chassis uses ABS polymer for its light weight, durability, and excellent acoustical properties. A proprietary, optimized bass reflex structure is used, with every detail adjusted specifically for the acoustic guitar. Two-way coaxial speaker features a powerful eight-inch speaker plus tweeter. From a bountiful low range to clear highs, the output is transparent-sounding while ensuring a sense of volume. The INSTRUMENT channel provides a three-band EQ with BASS, MIDDLE, and TREBLE, while the MIC channel provides an independent two-band EQ with BASS and TREBLE. Independent effects are also provided for each channel: the INSTRUMENT channel features high-quality chorus, reverb, and chorus+reverb, while the MIC channel features reverb. The power amp section also has a built-in limiter. For inputs, this amp provides not only INSTRUMENT, but also MIC with phantom power. Each input has an independent VOLUME control. The INSTRUMENT input also has a PHASE switch that reduces acoustic feedback. Additionally, there is an AUX IN jack for connecting an audio player or rhythm machine for jam sessions, a LINE OUT jack that can be connected to PA system, and a headphone jack that is ideal for practicing at home.
