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.
