Introduced in January 2019, the VX15 GT was a practice amp with amazing capabilities. While sharing the preamp and control facilities of it's larger brother, the 50 watt Vox VX50 GTX, the Vox VX15 GT was rated at 15 watts RMS.
ABS Plastic Enclosure
The VX15 GT featured a lightweight but durable injection molded black ABS plastic cabinet with a wood baffle, black "shadow diamond" grill cloth and a 6.5" speaker. The enclosure included a bass reflex port to enhance low end response. This unique cabinet design, combining plastic and wood, allowed the VX15 GT to weigh about eight pounds.
Nutube
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.
Korg has been a leading manufacturer of portable keyboards since the early seventies. Most modern Korg keyboards incorporate a vacuum florescent 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 to perform just like the triode in a 12AX7 tube. After years of research, Korg developed the dual triode Nutube 6P1 vacuum tube (seen at lower left) using these new technologies.
The preamp of the Vox VX15 GT utilized a Korg Nutube 6P1. The turquoise glow emanating from the Nutube 6P1 can be seen through a series of small holes located on the control panel.
Amp Modeling Using Virtual Element Technology
The VX15 GT featured a digital amplifier modeling engine called VET, or Virtual Element Technology. VET didn't just aim to just get the "essence" of the tone of the worlds most iconic guitar amplifiers, it modeled how the electronic components and circuit designs interact in these classic amps.
Ten VET amp models were included: Deluxe, Boutique Classic, Boutique Overdrive, Vox AC30, Vox AC30TB, Brit 1959, Brit 800, Brit VM, SL-OD and Double Rectifier. An eleventh position on the rotary amp model selector offered a line input with flat response suited for acoustic guitar.
To further increase tonal flexibility, the "Program" button provided storage for three tonal variations of each VET amplifier model. The first selection was labeled "Preset" and was designed by Vox to complement the tone of the amp model. The other presets were labeled "User A" and "User B." These presets could be adjusted and stored to personal taste. A series of three LED lamps indicated which preset was selected.
Modulation Effects
The VX15 GT included four modulation effects: Chorus, Flanger, Org Phase and Tremolo. The "Modulation Effects" control knob was divided into four sectors. One modulation effect was assigned to each sector of the control. Rotating the "Modulation Effects" control clockwise from "Off" advanced through the four modulation effects. The "Tap" button adjusted modulation speed.
Delay/Reverb
The VX15 GT also included four delay effects: Analog Delay, Tape Delay, Spring Reverb and Hall Reverb. The "Delay/Reverb" control knob was also divided into four sectors. One delay effect was assigned to each sector of the control. Rotating the "Delay/Reverb" control clockwise from "Off" advanced through the four delay/reverb effects.
Guitar Tuner
Depressing the "Tap" button for several moments engaged the guitar tuner. It used the three LED lights from the Program section to indicate if a guitar string was on pitch.
Headphone/Line Out Jack
The VX15 GT included a 1/8" line out jack that included a cabinet simulator.
Optional Foot Switches
Vox offers two optional foot switches for the VX15 GT. The two button VFS2A foot switch allows the remote selection of two presets. The five button Vox VFS5 foot switch expanded program selection to two banks of four programs, or a total of eight.
