Il Cannone A Options During the development phase of Il Cannone violin with musicians we identified two trends in terms of player response. One group of violinists preferred the directness and focus of a set using one prototype A whilst the other group chose the warmer and broader feel of an alternative A variant. Warm & Broad or Direct & Focused? We have completed an extensive trial testing Il Cannone A options. We listened to your feedback & are pleased to announce that the Il Cannone Warm & Broad A is now available as a permanent option. See some of the musicians who participated in the testing process below. All images submitted by the participants.
