Welcome aboard!
Thanks for choosing the VOX MINI3. To ensure a long and
trouble-free relationship with your new amp, please read
this manual carefully, use the amp as directed and keep the
manual for future reference.
We hope you enjoy the great sound of the VOX MINI3!
Main features
l The compact MINI3 features three watts (3W) producing
stellar tones inherited from the VOX Valvetronix series
(VT15, VT30, VT50, VT100).
l This portable amplifier is powered by six AA-size alkaline batteries or the included AC adapter, enabling you to
play anywhere. During battery operation, you can play
for up to 10 hours.
l In addition to four high-quality, all-time favorite effects,
the amplifier features four delay and reverb effects that
simulate acoustic reverb. The amplifier also features a
user-friendly interface, enabling you to adjust the tone
via a single knob.
l The TAP button enables you to easily set the delay time
in sync with the tempo.
l The built-in tuner function enables you to tune a guitar
connected to the INPUT jack.
l Inputs include an AUX IN jack, for connecting an external
audio device (CD, MP3 player, etc.), and a MIC IN jack,
to which you can connect a microphone. You can play
along with recorded music or accompany your vocals on
You can also adjust the send level from the MIC IN jack
to the DELAY/REVERB effects by using the dedicated
This section describes the basic setup of your amplifier.
NOTE: This manual also describes safety precautions and
functions. Be sure to read the entire manual.
1. Turn the MASTER volume on the amp all the way
Installing Batteries
Remove the battery compartment cover located on the bottom of the unit by pulling the ribbon. Insert six AA-size
alkaline batteries as shown in the figure. Be sure to observe
the correct polarity.
NOTE:Batteries are not included. You will need to purchase
them separately. Never use any type of battery other
than alkaline batteries.
2. Install batteries in the amplifier. Alternatively, you can
connect the included AC adapter to the DC12V jack on
the rear panel, then plug the adapter into an AC outlet.
3. Plug your guitar into the INPUT jack on the top panel. If
you also plan to use a CD or MP3 player, or a microphone,
connect the player to the AUX IN jack or the microphone
to the MIC IN jack on the top panel.
4. Turn on the STANDBY switch.
5. Slowly raise the MASTER volume to a desired level.
NOTE:Be sure to install batteries in the correct orientation.
Replacing the Batteries
If the indicator located above and to the left of the STANDBY
switch becomes dark, replace the batteries.
NOTE: If the battery level becomes low, noise may be generated.
NOTE:Depleted batteries must be removed from the MINI3
immediately. If you leave them in, malfunctions such
as battery leakage may occur. You should also remove the batteries if you will not be using the MINI3
for an extended time.

Amp Models and Effects
This section describes characteristics of each amp model
and effect.
AMP model
This models the clean channel of a high-quality amp that
was produced only on special order, and was known as the
overdrive special. With a beautifully rounded low range, a
sharp midrange attack, and a sweet treble register, this is
ideal for single coil pickups.
BLACK 2x12
This models a black-faced 2x12" combo amp that has become
an indispensible item for country and blues players. Its tight
and clean sound provides deep piano-like bass tones, and
will deliver the classic Chicago blues tone particularly when
used with single coil pickups.
TWEED 4x10
This models a 4x10" combo amp from 1959 that was originally designed for bass guitar. Its smooth and crisp overdrive
sound will respond sensitively to your picking dynamics
and to the volume of your guitar.
This models channel 2 of the VOX AC15 (1x12", 15W), which
was manufactured in 1962 and was a big hit for its compact
cabinet, power, and great tone – along with then-popular
British bands.
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.
UK '70S
This models the high treble channel of a hand-wired amp
head made in England during the early 60’s. Raising the
volume of this 50W output amp all the way produces the
crunch that will forever be the sound of rock ‘n’ roll.
UK '80S
This models a UK-manufactured 100W single-channel head
with master volume made in 1983. Turn the GAIN control all
the way up to get that thick, snarling hard rock and heavy
metal sound that dominated the 80’s.
UK '90S
This models the high-gain channel of a modern 100W amp.
While individual notes are clearly defined, it delivers a monster sound that’s quite aggressive and arrogant.
This models the modern high-gain channel from a wild
beast of a high-gain amp. Its deep and loose low-end, sparkling highs, and monstrous gain are ideal for guitars tuned
as low as possible, or for metal acts wielding seven-string
This models the overdrive channel of a snakeskin-covered
100W amp head made in 1991. With an open low-end and a
compressed mid/high range, its powerful and heavy sound
delivers a forceful tone that will not break down even with
the most extreme gain settings.
This model features two-band tone controls that create a
pure clean tone with no distortion. Use the GAIN knob to
adjust the volume level for the low range, and the TONE
knob for the high range.
This models a compressor that features a clean, percussive,
and mellow sustain. Suitable for pop or funk rhythms.
Use the knob to adjust the amount of sustain.
This models a standard analog chorus that adds a rich spaciousness to the sound.
Use the knob to adjust the modulation speed.
This models an analog flanger that creates a sound with a
peculiar swooshing effect like a jet engine.
Use the knob to adjust the modulation speed.
This models a typical tremolo built into a standard U.S.
combo amp that changes the volume up and down cyclically.
Use the knob to adjust the tremolo speed.
This models an analog delay that uses a bucket brigade
device (BBD). The sound quality is low fidelity, but its warm
sound is popular among musicians.
Use the knob to adjust the mix amount of the delay
Use the TAP switch to set the delay time. The longest possible delay time is 1,486ms.
This models a popular analog tape echo.
Tape echo was originally created by using a playback head,
and the delay time was adjusted by modifying the motor
speed. The knob and switch functionality is the same as
that for the ANALOG model.
This models a spring reverb inside a guitar amp.
Use the knob to adjust the mix amount of the reverb
Use the TAP switch to set the reverb time.
This is a standard room reverb that contains a lot of initial
reflection. The knob and switch functionality are the same
as the SPRING model.

You’ll need to unplug your headphones or cable from
the PHONES jack to do this, since plugging something
into this jack automatically mutes the amp’s speakers.
If there’s still no sound from the amp, go to “There’s
no sound coming from the amp.” If you do hear sound,
check the headphones or cable you are hooking up to
this jack.
The effects cannot be applied to the sound.
