Sound Pure's Take

The AcoustiCube is one of the most capable acoustic guitar amplifiers on the market. In addition to its phenomenally natural reproduction of acoustic guitar tone, it has a wealth of options to sculpt your sound. From an enormously large library of extraordinarily useful effects to its sophisticated eq controls, this amp can create any sound you can imagine and then some. You can also hook up your AcoustiCube to your computer via the built-in USB connection and tweak effects parameters to change your favorite preset settings as well as create your own custom effects. Housed in a lightweight, portable cabinet, this is the ultimate tool for any acoustic guitar enthusiast on stage or in the studio. Don't miss your chance to own AER's flagship acoustic amplifier at a fraction of the new cost! Contact Sound Pure today for more information.

From AER Amps

The AER AcousticCube 3 Guitar Amp is an amazing feat in a small box like this. For more than 10 years this little giant has set standards and AER have done their best to push the limits further and further.

In its 3rd generation now, AER have implemented advanced dynamic control technology and have extended the dynamic range substantially. The two-way speaker system is an incredible improvement. It allows a much clearer and defined bass response and much lighter, more vivid reproduction of the complete range up to finest texture.

The Cube 3 amplifier is a full two-channel version now allowing identical features on both channels. It needed a face-lift for more operational clarity and to allow additional important controls on the front panel.

In essence AER has combined all the suggestions of Cube enthusiasts over the years with all their knowledge and experience … without compromise … and are now pleased with version 3's improvements to sound, dynamics, presence, and natural sound. Not to mention the features.

Tone Control:

The AcoustiCube 3 amp's three band tone controls are active and constructed to fulfill the specific requirements of both acoustic instruments and other sources. The color switches activate a mid-cut-treble-boost-filter that especially suits finger picking.

AER DSP 4 Digital Effect — internal effect

The AcoustiCube 3 has a built-in (internal) digital 32bit AER-effect processor. With the effect—program—endless-encoder you can choose between 100 (0-99) effect programs (factory settings: chapter 6). The number of the chosen effect can be seen in the two-digit display. The direction in which you turn the control does not matter.

You can connect your AER AcoustiCube with a computer via USB-cable, change the effect program parameters that suit your requirements, make combinations and store them under a new name. Two of the 100 effects can be stored and recalled via the AER footswitch. You can select an effect and by pressing the program-encoder on your AcoustiCube amp, this effect is stored.
