Manufacturer's Description from AER

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.

AER Amps

About Manufacturer

AER Amplifiers are one of the world’s leaders in acoustic instrument amplification. Whether you’re playing archtop, acoustic guitar, nylon-string guitar or bass, AER places an emphasis on clarity, fidelity and portability. Please feel free to contact Sound Pure to determine the right AER amp for you.
Since 1986 Susanne Janz-Eisenmann, Michael Eisenmann and Udo Rýsner have been working together in a team in various lines of the music sector - as retailers, in the repair field, as acoustic specialists and developers. "Learning by doing", the "passion" for acoustic instruments, "good sound" and the "daily removing of obstacles" have shaped the development from the beginning.

One does not become a manufacturer overnight. Exceptional solutions do not just come out of the blue. To commit oneself implies: a wave starts rolling which is difficult to keep up with, even when trying hard.

Production hall, machines, finding one's self, staff, manufacturing processes, being on the wrong track, not giving up, work safety, reliability, series production, setbacks, further developments, mistakes, customer contacts, expectations, disappointments, international contacts, trade fairs, wholesalers, multilingualism, operation instructions, warranty claims, product line, competition, business letters, financing, marketing strategies, remaining true to oneself - a great deal of things at once. A whirl between euphoria and stackoverflow.
Since 1992 they have been working to make AER the hallmark of acoustic amplification. High-quality components with minimal tolerances, sophisticated circuit technology, calculating constitute the basis to convert plans into melodious sound. More than 20 employees are busy equipping, checking, documenting, installing, assembling, and checking all over again. In the company electronics still means a great deal of manual work. Measuring and simulation do not suffice. In the end, every single amp is played and checked for sound and function.
They work for the musician's everyday task, and that is "live"
