Based on the elliptical enveloping clamp design first found on the u-mount series, this mic stand accessory tray is a natural adaptation of that versatile system. A single oversized thumbscrew secures the mount in seconds to any round tubing from ½ - ¾?, like upper shafts of microphone stands. The accessory tray is a perfect catch-all for all of your picks, capos, tuners, slides, your set list, or a drink! We?ve taken the design one step further and added a threaded end to the mounting bar, which allows you to mount an additional mic... perfect for miking an acoustic instrument!
