Inspired by the Indian sitar, the bridge saddles of the "Michel Gentils signature" guitars made by Julien Jalaguier are worked with precision to the hundredth of a millimeter. Mastered today by very few luthiers around the world, this multi-millennial technique consists of "sculpting" the sound to achieve maximum harmonic richness and give a soul to the instrument: the "jawari". This adaptation of the sitar saddle to the guitar is the trademark of the "Michel Gentils signature" guitars. Upon leaving the workshop, each guitar is then validated by Michel Gentils in terms of settings and "jawari". Halfway between traditional lutherie and innovation, between West and East, new avenues of sound exploration are available to guitarists.
