We hope that this short synopsis could serve as a guide for the musician for the acquisition of an S-bocal. Unfortunately, a generally applicable evaluation cannot be given here. In the end the decisive factor for the optimum sound and acoustics of an instrument is the musician himself as well as the tube used, the intonation and the playing technique. It can be assumed, that each and every instrument reacts individually on the different types of S-bocals. Therefore, we recommend you to use our service to order our assortment for selection without obligation or to test your S-bocal directly in our workshop, before you buy it. With great pleasure we are willing to assist you in the acquisition of your HECKEL-S-bocal.
