Personal studio system module with Brass Resonance Modeling.
The Yamaha SBJ SILENT Brass Personal Studio system module features Yamaha’s exclusive Brass Resonance Modeling which offers the natural acoustic tone you hear when playing without a mute, making it feel as though you're playing mute free. The updated STJ Personal Studio module allows you to connect to a computer or smart device via a supplied cable to allow you to record or take part in online lessons at home, without the need of an audio interface.
