Introduction Welcome! Thank you for purchasing the VOX VT15, VT30, VT50 or VT100 Valvetronix amp. To help you get the most out of your new amplifire, please read this manual carefully. Get ready to enjoy the VT-series amazing guitar sounds! Main features ➢ The VT-series use Valve Reactor technology, and feature a power amp circuit containing a 12AX7 (ECC83) dual triode valve (“vacuum tube”) that would normally be used in a preamp.
Signal path Your guitar sound passes through the following sections. Refer to “Top and rear panels” (p.8) in conjunction with this illustration.
Quick start This Quick Start section is for those of you who would like to start using your new amp right away. This manual contains information that will help you take full advantage of your Valvetronix amp, so be sure to read the rest of it after you’ve read the Quick Start section. HINT: Illustrations of the top panel and rear panel are provided in “Top and rear panels” (p.8), so refer to them as you try out your amp. Setup 1. Turn the [MASTER] volume control on the amp all the way down. 2.
Checking out the preset programs 1. Press the top panel [PRESET] switch. The PRESET LED will light up(Preset mode). 2. Turn the [AMP] selector to select an amp model. A preset program for a sound that is typical of each amp model will be recalled, and the GAIN, VOLUME, TREBLE, MIDDLE, BASS, and effect settings will switch automatically. HINT: The amp models are organized into two banks, each bank containing eleven models (a total of twenty-two). Press the AMP switch to change banks.
Top and rear panels In this chapter we're going to take a look at the top and rear panels of your Valvetronix amp. A. Top panel 2 The illustration shows the VT100. 1 1. 4 3 5 INPUT/PHONES section INPUT jack This is where you plug in your guitar. PHONES jack Use this jack if you want to output directly to a mixer or recording device, or when you want to use headphones.
In Preset mode (i.e., when the PRESET LED is lit), you can recall preset programs that contain sounds and effect settings that are typical of each amp model. [GAIN] control This adjusts the pre-amp gain of the selected amp model. [VOLUME] control This adjusts the volume of the selected amp model. [TREBLE], [MIDDLE], [BASS] controls These adjust the tone for the high, mid, and low-frequency ranges. The change produced by each control will differ depending on the amp model that you’ve selected.
[TAP] switch, LED This sets the speed of modulation-type effects such as Chorus or Flanger, or the time of Delay or Tape Echo effects. The interval between two presses of the switch will be set as the time. The LED will blink at intervals of the specified speed or time. HINT: To set a precise time that matches the tempo of a song, press the switch several times in rhythm with the song. HINT: You can also adjust the speed or time setting by holding down the [TAP] switch and turning the [EDIT] knob (EDIT 2).
[CHANNEL] switches, LEDs Use these to select channels. The LED of the selected channel will be lit. To save a new program, hold down the desired [CHANNEL] switch for one second or longer. 5. Power switch [POWER] switch When the power is on, the indicator located above the switch will be lit. B. Rear panel VT15/VT30 1 The illustration shows the VT30. 2 3 VT50/VT100 1 The illustration shows the VT100. 2 3 4 5 (VT100 only) 1. AC power connector This is where you connect the included power cord.
3. [POWER LEVEL] control This adjusts the output wattage of the power amp. VT15: less than 0.2W – 15W VT30: less than 0.2W – 30W VT50: less than 0.2W – 50W VT100: less than 0.2W – 100W NOTE: The power level setting is not saved in the program. This allows you to output at a range of volume levels without impairing the fat and warm sound (distinctive of classic tube amps) that is produced when you raise the drive of the Valvetronix amp’s power stage.
About the three operating modes The VT-series contains three preset programs – basic, effected, and song – for each of its amp models (giving you a total of 66 programs). You can select these simply by switching the VT-series to Preset mode and using the [AMP] selector. There are also eight channel programs (user programs) that you are free to rewrite; use the [BANK] switch and [CHANNEL] switches or foot switch to switch between these.
Switching to Manual mode If the MANUAL LED is dark, you’re not in Manual mode. Press the [MANUAL] switch; the MANUAL LED will light, and you’ll be in Manual mode. NOTE: In Manual mode, adjusting a parameter whose setting is not determined by the position of a knob (i.e., the effect parameters and the noise reduction setting) will save that setting automatically. Those settings will be recalled the next time you enter Manual mode.
Creating and saving sounds You can create a sound either by starting with an existing program that’s close to what you have in mind and then editing it, or by creating the sound “from scratch” (i.e., from an initialized state). Creating a sound Here’s how to create a sound from scratch. 1. Either select a program in Preset mode or Channel Select mode, or put the VT-series in Manual mode. HINT: It doesn’t matter which program you select, since you’re creating the sound from scratch. 2.
HINT: For details on the effect types, refer to “Explanation of the amps and effects” (p.19). 8. If you want to use reverb, turn the [REVERB] knob to adjust the reverb mix amount. Adjusting the noise reduction Here’s how to adjust the way in which noise is suppressed. NOTE: Noise reduction is specified individually for each program. In Preset mode or Channel Select mode, the noise reduction setting will be lost if you switch to a different program or to Manual mode or turn off the power before saving. 1.
Checking the original values saved in a program The original value indication lets you check the parameter values that are saved in a program. When you turn a knob to change the value of a parameter, the PRESET LED (if you’re in Preset mode) or the LED of the selected channel (if you’re in Channel Select mode) will momentarily go dark when the edited value matches the value that’s stored in the program.
Using a foot switch (VOX VFS5) If you connect an optional foot switch (VOX VFS5: 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. Malfunctions or damage may occur if you connect or disconnect the foot switch while the power is on. NOTE: Do not press two or more foot switches simultaneously. Doing so may cause malfunctions.
Explanation of the amps and effects This section explains the twenty-two amp models and the effects. Amp models Here we will explain the twenty-two amp models that were specially selected for the Valvetronix amp from numerous great-sounding amps. Much time was spent on selecting the amps to be modeled, and there were repeated consultations between staff members, much advice obtained from pro musicians and guitar specialists, and countless hours of listening and auditioning.
A-7: AC50CP2 The VOX AC50CP2 classic plus combo is VOX’s new concept in all-tube amps. This amp models the more high-gain channel 2 with the “Fat Switch” turned off. A-8: UK 25TH Based on a UK-made 100W head, this amp was created for a famous guitarist known for his amazing tone, slash rhythms, and liking for silk hats. If you have a desire for ultimate metal tones, this amp will be the perfect choice.
B-5: AC30TB This models an AC30 amp with the “top boost” circuit that was included as standard starting with units produced in 1964. It delivers a smooth and refined top end, majestically deep overdrive, and a rich and brilliant clean sound. B-6: BOUTIQUE OD This models the overdrive channel of a 100W high-quality amp that was produced only on special order, and known as the overdrive special. The wonderful sustain obtained by raising the [GAIN] control is smooth and soulful.
Effects The VT-series provides eleven of the most popular effects (including multiple effects) in addition to reverb. You can set the SPEED parameter of the modulation effects or the TIME parameter of the delays simply by pressing the [TAP] switch twice at the desired interval. Use the [EDIT] knob to set the most important parameters, and make additional detailed settings by turning the [EDIT] knob while holding down the [TAP] switch or [BYPASS] switch.
CHORUS This models a standard rich-sounding analog chorus unit. TAP “SPEED” Adjusts the modulation speed in a range of 0.1...10 [Hz]. EDIT1 [EDIT] “DEPTH” Adjusts the depth of modulation. EDIT2 [TAP+EDIT] “SPEED” Lets you use the knob to make fine adjustments in the delay time. EDIT3 [BYPASS+EDIT] “MIX” Adjusts the mix amount for the effect sound. HINT: The CHORUS+DELAY combination effect does not allow you to adjust the SPEED, DEPTH, or MIX parameters (these are set to appropriate values).
PHASER This models a popular analog phaser that was packaged in a banana-yellow box. TAP “SPEED” Adjusts the modulation speed in a range of 0.1...10 [Hz]. EDIT1 [EDIT] “DEPTH” Adjusts the depth of modulation. EDIT2 [TAP+EDIT] “SPEED” Lets you use the knob to make fine adjustments in the speed. EDIT3 [BYPASS+EDIT] “RESONANCE” Adjusts the amount of resonance. ROTARY This models a rotary speaker. TAP “SPEED” EDIT1 [EDIT] EDIT2 [TAP+EDIT] “DEPTH” “SPEED” Adjusts the modulation speed in a range of 0.8...
Troubleshooting 1. Power does not turn on when you turn the [POWER] switch on ➢ ➢ ➢ ➢ Is the power cable connected to the rear panel AC power inlet? Is the power cable connected to an AC outlet? Could the AC outlet be malfunctioning? Could the power cable be damaged? 2.
4. No sound from the PHONES jack ➢ Could the top panel [MASTER] volume be turned down? ➢ Check whether sound is output from the amp. To do this you must disconnect the PHONES jack, since sound will not be output from the internal speaker if headphones or a cable are connected to the PHONES jack. If no sound is produced from the amp, check the items listed in “No sound from the amp,” above. If there is sound from the amp, check whether your headphones or cable might be broken or malfunctioning. 5.
