Want to play when and where you like, without being confined to a time or place? Our next generation Silent Brass system makes it possible...The new Silent Brass packs include a smaller, lighter, even more playable pickup mute which works together with the new Personal Studio module, which features our exclusive Brass Resonance Modeling. Used together, you'll feel and hear the natural acoustic tone and response of non-muted playing - without disturbing friends and family.Silent Brass Pickup MuteThe Pickup Mute combines a high-performance mute with an internal microphone to pickup sound. Significantly smaller and lighter than previous versions, the mute offers superior muting performance, delivers excellent intonation over a wide pitch range, and natural playability. A new compact design now lets you put your instrument in its case with the mute in the bell.Please note that the Pickup Mute may not fit some instruments with significantly different bell shapes or bell diameters. Please check before purchasing.Brass Resonance ModellingThe Silent Brass Personal Studio module features our unique Brass Resonance Modelling technology, which recreates the sound of non-muted brass instruments to correct your instrument´s tone when the Silent Brass Pickup Mute is in place. The resulting sound is so realistic, it´s virtually indistinguishable from the un-muted tone.The Silent Brass Offers More EnjoymentConnect the output from an audio player, smartphone, et al to the AUX IN jack on the Personal Studio and enjoy playing along with your favorite recordings or 'minus one' practice aids.
