Selling one of my wonderful AER Basscube amps. These small and powerful cubes are designed to be used with double basses AND electric basses. I personally find them extraordinarily well for old Fender basses. The sound is deep, warm, full and even throughout the whole spectrum and supports the natural tone of even a good old electric bass in the best way.

This Basscube is version 1 - compared with the version 2 this model has the heavier wood construction and the 3 (instead of 2) input channels. Both models are fully loaded with all features you would need to control your bass sound in any environment: 3 input channels, aux input, Notch filter, compressor (very subtle and nice), phantom power, etc etc. Version 1 is not available anymore. Version is offered for [color=#FF0000][b]retail price 2,649.61 GBP / 3.175 EUR[/b][/color] (Thomann) and up !! These amps are a rare find on the 2nd hand market and for a good reason !

The exeptional small dimensions might lead you to underestimate this cube. You won't believe how full and loud these small amps are (that's true for all AER amps including the amazing mini combo AER Amp One).

Condition is technically 100%. There are some signs of wear on the bottom and some dust on the other sides but nothing is damaged. The amp was at AER for a full check in 2011 and works 100% reliable.

This is an extract from the AER manual:

We followed radically different paths when we set out to realise our tone ideas in order to make the bass sound the way it wants to sound.

• A controlled switched mode power supply clocked to 200 kHz supplies the 350 watts/8 Ohm bass power amplifier with adequate constant voltage, independant from the load current. Its efficiency is exceptionally high. Among other things, this makes it possible to provide this degree of performance in such a small cabinet without causing thermal problems.

• The analogous signal processor monitors the signal so that full power-amplifier performance can be called upon without the “headroom” that would normally be necessary. That saves space and weight, is gentle to the loudspeaker and provides for constant and definite conditions in the power amplifier. Since a “closed system” (power amplifier, processor and loudspeaker) is at issue, it is possible to match all components involved optimally, thus ensuring a maximum of effectiveness without overstraining the system. We approach the limits without exceeding them.

• We chose a 12” B&C die-cast long-stroke speaker. This 12” loudspeaker is particularly suitable for bass reproduction in small bass-reflex cabinets. Reproduction characteristics, capacity and efficiency are interrelated in such a manner that special bass speakers are always somewhat softer (by about 3 dB) than universal speakers. The speaker has been subjected to electrical and mechanical testing according to AES (Audio Engineering Society) standards.

• The cabinet must withstand enormous strains. It it made of 18 mm birch multiplex (13 ply) and is grooved and glued with waterproof glue. The loudspeaker is contained in a bass-reflex chamber separate from the electronic unit so that everything is mechanically decoupled.

• The BASSCUBE is “two-way-active”, that is, there is an additional dome tweeter with active frequency crossover and its own power amplifier with 60 watts to 8 ohm. The tweeter is mounted on a multiplex traverse in the middle of the 12” bass loudspeaker (coaxial construction). The “combo-amplifier” is hence a full-range 2-way active speaker system with audio quality.

• Furthermore, the BASSCUBE is constructed with 3 channels (supplemented by Aux-in). This makes complicated set-ups using a piezoelectric pick-up, magnetic pick-up and microphone, all linked to one amplifier, through which you can also sing.

• Further features include:
- 48 V phantom source for a microphone
- 9 V phantom source for bass electronics (through a stereo cable)
- FX-loop, mono, parallel
- Notch filter with adjustable cut and frequency
- switchable compressor
- variable DI-out to XLR
- line-out, tuner-out, headphones-out
- footswitch (FX-loop on/off)
- variable tape-in (RCA phono plug)
- active subwoofer out
- passive ext. speaker out
- groundlift & voltage select
