Our hollow body cello is a travel acoustic instrument with correct ergonomics as a regular cello. Its hollow body is a precision design project that acoustically responds to the interplay of the instrument’s vibrating parts: sound board, bridge, and sound post. Its setup aims at a perfectly amplified acoustic result. For this reason we designed a specific active electronics. Our pickup and preamp, while highlighting the instrument’s acoustic qualities, are easy to use, and offer the musician control and independence from sound technicians.

Size & Weight

Our cellos have the exact dimensions of a traditional instrument.

The 5-string cello has a wider neck section and a fingerboard with a tighter curve to provide better uniformity of action. The low-E string is made by Thomastik with our specs for greater clarity.


CELLO is offered with anactive electronics system, powered with a 9V alkaline battery, andtwo sound sensors: one polymeric pickup, placed under the bridge, and a bridge-mounted microphone.
The proprietary active system is conceived to enhance the acoustic qualities of the ALTER EGO instruments. The two sound sources each have its own volume control so that a musician can easily shape their own desired sound.
In addition to the volume, a switch control for the microphone provides as quick adjustable “arco” setting.
