Thank you for purchasing the AAD CUB Acoustic Guitar Amplifier. A
great deal of dedication and passion went into designing and building this
no compromise, high performance compact-combo amplifier. It was
conceived to be a dedicated amplifier for the “connoisseur” guitarist.

OVERVIEW OF THE CUB
The CUB is not your usual combo amp. On first appearance it may be mistaken for what it is
because of its diminutive size. Don’t let this fool you, this is a very high performance amplifier
designed to give the utmost fidelity for acoustic guitar or any other lead musical instrument
where clean sound and absolute fidelity are paramount. AAD has pushed the envelope in
creating what is the smallest serious guitar amplifier currently available.
Rather than cram it with gimmicky features to enhance marketing, we decided to go all out on
making the best small amplifier money can buy. Nothing this small, with this performance has
ever been created before. To the working musician this amplifier will not only give sound
quality beyond expectations but in practical terms of transportation and storage; this amplifier
will be invaluable.
FEATURES
•Switchable high impedance/high gain input OR low impedance/low gain stage.
•3 Band EQ designated for guitar.
•FX Send Return sockets.
•Tuner out.
•Pre-amp Output.
•Balanced Line Output with ground lift.

PANEL DESCRIPTION
1. Input Socket
Accepts standard mono ¼ inch guitar instrument cable.
2. Input level switch
This switches the input sensitivity. 0db with passive pickups or -10dB: output from an
additional pre amp.
3. Level Control
Controls volume of amplifier.
4. Bass Control.
5. Mid Range Control
6. Treble Control
7. FX Send
Connect the FX send to auxiliary FX unit input.
This can also be used as an additional line out if necessary.
8. FX Return
Connect the FX Return to auxiliary FX unit output.
9. Line Out
These are used for driving a second amplifier.
10. Tuner Out
Connect to instrument tuner. This output can also be used as an additional line out.
11.XLR Balanced Line Out.
This is an ultra-low impedance (200ohm) balanced line out for use with recording or PA mixing
consoles.
12. Ground lift Switch
When there is a difference in grounding between audio equipment, it can cause what is
known as a ground loop. This will cause an audible hum or buzz through the speakers or
main PA speakers. Using this switch will break the ground loop and therefore eliminate
any hum.
13. AC Power On/Off Switch.
14. AC Power input and AC fuse holder.
Connects the amplifier to AC power supply. Always use a grounded plug and make sure
5

the AC cable is more than 3A rating at 250-volt AC. If you require a longer AC power cord,
we recommend you use the AAD heavy-duty 20 foot power cords. These are available as
an accessory. Use a slow blow ¾ inch fuse rated at 2.5 amps.
OPERATION & POSITIONING
TURN THE VOLUME DOWN on the CUB before plugging in your instrument.
Positioning the CUB for Best Sound
It is recommended that you place the cub on a solid object or dedicated stand for best sound
and projection. Do not place on a high microphone stand as it will be unstable and easily
topple over.
TRANSPORTING AND STORING THE CUB
When transporting in a vehicle, it is recommended that you use an external case or heavy-duty
cover to prevent it being damaged by falling over or other objects falling on it. The Cub has an
optional padded carrying bag as an available accessory.
When Storing:
•Keep the CUB in a dry location preferably at room temperature.
•Do not store the CUB in temperatures below -20 Degrees C or above 40 Degrees C.
•Do not allow it to get wet. If this occurs, never turn it on in this condition.
•Do not leave the CUB connected to a power source for long periods of time.
