Cello Hollowbody

Our RES Cellos maintain the same Alter Ego craftmanship standards as in the past. They are designed with every detail respecting traditional construction principles. Its resonance chamber is in Balkan maple and its soundboard in Italian red spruce from Val di Fiemme. Its soundpost, as in a traditional instrument, plays an important role in tone adjustment. Our RES Cellos are rich in harmonics and are crafted to provide an immediate physical response so each musician can easily find their distinctive sound. The neck is in select Balkan maple. Our master luthiers carefully fine-tune each instrument for maximum playability along the entire fingerboard length. All RES Cellos are equipped with the Alter Ego Neck System that allows to quickly adjust the neck angle/string action. They also have a removable neck to fit in the ultra-compact soft travel bag they come with.

RES is offered with an active electronics system, powered with a 9V alkaline battery, and two 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 their own volume control so that a musician can easily shape their own desired sound.
In addition to the volume, a switch control (optional) for the microphone provides a quick adjustable “arco” setting.


On request, we make custom 5- string and/or left-handed instruments.

Our 5-string RES Cellos have a slightly wider neck and a fingerboard with a tighter curve for better playability across all five strings.

The low-F string is made by Pirastro for greater sound clarity.


External headphones preamplifier.


All instruments come with a standard removable neck (thanks to the “Neck System”) for extra portability. The travel bag is 75 cms long (29.5 in.) and easily fits in an aircraft overhead compartment.

String action
The Alter Ego neck system allows to adjust string action by changing the neck angle. No bridge adjusters are needed anymore. The system is quick and precise and can also be done during a performance.


No preamp added, no equalization, no sound modification. We recommend listening with headphones. Credits: Mike Richmond
