Vox VX50AG Acoustic Guitar Amplifier with Nutube Technology -The Vox VX50AG combo amplifier has a hybrid design combining a 50 watt Class D solid-state power amp with a Nutube powered preamp featuring digital chorus and reverb.

ABS Plastic Enclosure
The VX50AG features a lightweight but durable injection molded ABS plastic cabinet with a wood speaker baffle. This unique cabinet design, combining plastic and wood, allows the VX50AG to weigh less than 10 pounds. The closed back two-way VX50AG enclosure includes a two-way coaxial 8" speaker with a center mounted tweeter.

The preamp section of most tube guitar amplifiers will include at least one 12AX7 tube. The 12AX7 was designed as a "dual triode," meaning that it includes two separate circuits for amplification. Each of these triodes has three elements: a cathode, control grid and an anode. Amplification occurs when a flow of electrons from the cathode passes through the control grid to the anode. A filament wire located near the base of the tube heats the cathode to start this flow of electrons.

Korg has been a leading manufacturer of portable keyboards since the early seventies. Most modern Korg keyboards incorporate a vacuum floresecent display (or VFD) that offers a visual indication of the sound that is loaded and ready to play.

Korg discovered that a vacuum florescent display could be configured as a triode, complete with cathode, control grid and anode, to create amplification. After years of research, Korg developed the dual triode Nutube 6P1 vacuum tube (seen at lower left). It utilizes new technologies derived from vacuum florescent displays that allow the Nutube 6P1 to perform the same functions as a traditional 12AX7 tube.

The Nutube 6P1 offers a number of advantages over the 12AX7. The Nutube 6P1 is significantly smaller than a 12AX7. As it did not require a traditional filament heater, the Nutube 6P1 required a fraction of the current required to power a 12AX7. Unlike the 12AX7, the Nutube 6P1 remained relatively cool to the touch while in operation. Finally, the Nutube 6P1 offered a significantly longer service life than the 12AX7, perhaps never needing replacement.

The preamp of the Vox VX50AG utilizes a Korg Nutube 6P1 as a signal buffer. The Nutube offers the rich overtones of a traditional vacuum tube without the need for periodic replacement. The turquoise glow eminating from the Nutube 6P1 can be seen through a series of twelve small holes located on the control panel.

While the preamp circuitry of the VX50AG includes a 6P1 Nutube, the 50 watt power amp section was solid-state.

The VX50AG has two channels, Instrument and Mic. The Instrument channel has Volume, Bass, Mid, Treble and Effects controls plus a phase reverse switch. The Mic channel features an XLR input jack with switchable phantom power plus Volume, Bass, Treble and Reverb controls. A Master volume control adjusts the total output of the amp. Both channels include a red LED clip light to indicate the presence of excessive input signal levels.

The Effects control in the Instrument channel offers a single rotary control that swept between digital Chorus, Reverb or a combination of both.

Headphone/Line Out
The VX50AG includes a 1/8" line out/headphone jack that includes a cabinet simulator.
