Dear readers, in this issue I'd like to introduce you to an incredible instrument, which for its quality, concept and innovation represents an absolutely unique sample, where the restoration work has brought to light a number of structural features anticipating our contemporary research by more than one century. Let's think that, already around 1850, this great luthier, from the Marches region, designed this double bass with an adjustable pull-out neck by substituting the lateral bars placed between the resonating body and the neck. A particularly interesting solution is the joint at the bottom of the insert, which is an idea for a modern luthier. Beside the sinuous pear-form, which also constitutes a clear sign of Baldantoni's production, this instrument is absolutely original in each of its elements, such as the varnish, completely intact and bright, the refined Fs and the soft curl design. From an acoustic point of view, the instrument shows a number of brilliant and bright features, with its specific timbre richness in the highest registers, making it a perfect double bass for chamber or solo music. An almost identical instrument is played by Maestro Stefano Scodanibbio.
