  • Page 4: Introduction

    • This amp uses the VOX Valve Reactor power amp circuit featuring the EL84 (6BQ5) vacuum tube that amps such as the VOX AC30 use as their power tube, generating real tube amp sounds that reproduces the feel and tone of the original amplifier.
  • Page 5: Quick Start

    • You can use the effects loop jacks to insert an external effects processor in a loop connection. • The built-in auto tuner lets you tune a guitar that’s connected to the INPUT jack. • The AUX IN jack lets you connect a CD/MP3 player, enabling you to play guitar along with recorded music.
  • Page 6: Switching Between The User Programs

    Turn the AMP selector to choose an amp model. A preset program for a sound that is typical of each amp model will be re- called, and the GAIN, VOLUME, TREBLE, MIDDLE, BASS, and effect settings will switch automatically. HINT: The amp models are organized into four banks, each bank containing eleven models (a total of forty-four).

  • Page 12 5. FOOT SW (foot switch) jack You can connect an optional VOX VFS5 foot switch here. For more information on using the VOX VFS5, please refer to “Using the foot switch (VOX VFS5)” (p. 19). NOTE: You must connect or disconnect the VFS5 while the power is off.
  • Page 13: About The Three Operating Modes

    About the three operating modes Preset mode (recalling preset programs) In Preset mode you can use the AMP switch/selector to recall programs for each amp model: “basic” programs containing typical sounds for that amp model, “effect” preset programs, and “song” preset programs that replicate tones from hit songs.
  • Page 14: Channel Select Mode (Recalling User Programs)

    HINT: If an optional (separately sold) VOX VFX5 foot switch or VC-12SV foot controller is connected to the rear panel, you can use your foot to switch banks or channels.
  • Page 15: Adjusting The Noise Reduction

    Adjust the top panel knobs such as GAIN, VOLUME, TREBLE, MIDDLE, and BASS. Turn the VALUE knob to set the noise reduction. This setting is also saved in the program. For details, please refer to “Adjusting the noise reduction” (p. 15). HINT: Adjust the noise reduction so that there’s no unwanted noise when you’re not playing your guitar.
  • Page 16: Saving A Program

    NOTE: Depending on the guitar you’re using, raising the noise reduction too high may cause notes to be cut off. Press the TUNER (BYPASS) switch to make the TUNER (BYPASS) LEDs go dark. Saving a program When you’ve created a sound that you like, here’s how to save (write) it. HINT: If you’re saving to a channel in the same bank, proceed from step 3.
  • Page 17: Restoring The Factory Settings

    HINT: When you’ve found a program that you like, and are interested in knowing the actual settings, you can use this original value indication to find out. NOTE: The MASTER volume and POWER LEVEL controls are not pro- grammable, so the original value indication is not available for these controls.
  • Page 18: Using The Tuner

    Using the tuner The tuner function lets you tune a guitar that’s connected to the INPUT jack. HINT: If an optional (separately sold) VC-12SV foot controller is connected, you can use your foot to use the tuner function. For details, please refer to the VC-12SV owner's manual.
  • Page 19: Using A Foot Switch (Vox Vfs5)

    Using a foot switch (VOX VFS5) If you connect an optional VOX VFS5 foot switch (sold separately) to the rear panel FOOT SW jack, you’ll be able to switch banks/channels and turn effect bypass on/off using your foot. NOTE: You must connect or disconnect the foot switch while the power is off.

    Manual mode, or before turning off the power. Using a foot controller (VOX VC-12SV) If an optional (separately sold) VOX VC-12SV foot controller is connected, the number of user programs is increased to 16 (4 banks x 4 channels), and you’ll be able to select banks 3 and 4 which cannot be selected from the amp itself.
  • Page 21: Assigning A Function To The Expression Pedal (Quick Assign)

    For each program, you can specify the parameter that will be controlled by the expression pedal, and save the assignment. When you save a program, the position (angle) of the expression pedal at that moment is also saved as a value in the program.
  • Page 22: If You Don't Want Any Function To Be Assigned To The Expression Pedal

    Assigning the delay effect input level Use the MOD/DELAY selector to select “TAPE ECHO,” “A.DELAY,” or “CHORUS+DELAY,” and then use the DEPTH knob. Press the pedal switch while the pedal LED is blinking. Assigning the PITCH parameter of PITCH SHIFT Use the MOD/DELAY selector to select “PITCH,”...
  • Page 23 If you’ve assigned the PITCH parameter of the PITCH SHIFT effect, the mini- mum value will be “0” (no pitch shift) and the maximum value will be the current value. NOTE: If you’ve assigned the input level of the delay or reverb effect to the expression pedal, you won’t be able to change the minimum and maximum values.

    In contrast, the circuit newly developed for the VTX150 Neody- mium uses the EL84 (6BQ5) tube that's actually used as the power tube in amps such as the VOX AC30, meaning that it will function like a true tube amp. We’ve named this new technology “Valvetronix Pro.”...
  • Page 25: About The Amp Models And Effect Types

    About the amp models and effect types This section provides details about the amp models and effect types, such as pedal effect, modulation and delay effects and reverb effect. HINT: Each amp model’s GAIN (set by the top panel GAIN control) can be assigned to the optional (separately sold) VC-12SV’s expression pedal for control.

  • Page 28 7. UK ROCK STD (Standard) This 45W amp head was originally manufactured from 1962 to 1966, and was based on a tweed-covered bass amp. Its high-gain design was the beginning of the British amp tone revolution that continues to this day. SPL (Special) This models a UK-manufactured 100W single-channel head with master volume made in 1983.
  • Page 29 SPL (Special) This models the overdrive channel of a snakeskin-covered 100W amp head built in 1991. With an open low-end and a compressed mid/high range, its powerful, heavy sound delivers a forceful tone that will not break down even with the most extreme gain settings. CST (Custom) Designed to model the sound behind “POWER METAL”, this amp will crank.
