Acus Sound Engineering developed the Oneforstrings range to amplify the sound level of all acoustic instruments (notably acoustic and classical guitars) without altering their natural tone or resonance.

Oneforstrings amps are designed in minimalist style, with custom speakers, cabinets and highly reliable electronic components, all together capable of amplifying harmonics with natural tone.

Oneforstrings can also be used as a mini PA system. It is versatile and responsive, with a full range of functions specifically tailored for acoustic instruments. The product line, which is in continual development, consists of 4 amplifiers and an extension (for those who simply want to expand the sound reach of their own amplifiers without altering tone). Each unit differs from the other by channels and power, meeting all musicians’ requirements.

The innovative and stylish control panel features custom styled knobs, micrometric and functional. With equalisation, the tone controls modify frequency levels without suppressing the original note, even at lower and upper registers. The whole range also features multiple channels and reverb with processors exclusive to Acus. Also provided are line outs, mic and auxiliary inputs.

Acus’ designers, in consultation with top-flight instrumentalists, have developed bi-amplified power sections in the electronic components capable of creating a high bandwidth and slew-rate. Within the preamplifiers there are class A output stages in strategic positions, able to offer a very warm valve-like tone typical of studio amps.

The speakers are made in Italy to Acus’ specifications. Each model has the capacity to respond to changes in dynamics.

The compact and lightweight speaker cabinet is handmade in natural wood, with the correct size to power ratio. The natural version emphasises the minimalist design and look of Acus products. It is birch ply with a protective polyester top coat.

Other features such as the protective metal grille and carry handles are unique specifications, with real attention to design detail and functionality.


Equipped with two separate inputs (one Mic-Line and one Line), with controls for Gain/Volume, 3-Band EQ, Effect Send and Master Volume. The dedicated AUX input (with its own volume) allows for connetting an mp3 player or iPod. The system also features an electronically balanced direct output.
