The d:screet 4661 Heavy Duty can handle SPL 144 dB peak before clipping, making it one of the best miniatures for use on very loud and powerful instruments like snare drums, guitar, bass, speaker cabinets or other high-SPL sound sources. The heavy-duty cable relief and a thicker cable works well in live environments, which can sometimes be rough

Available in four colors: black and beige.
