I'd been looking at this for a while but wasn't sure if it would clash with my mute stand. Just tried this tonight in rehearsal, orchestral stand, with this shelf, and mute stand. My first impression from the rehearsal is that this is a great edition to my setup, Gives me a place put my glasses case, pencil, valve oil, and maybe even a small bluetooth keyboard (I use 2 iPads instead of paper sheet music). The mute stand fits below and works as normal, this doesn't encroach on the space at all. Wish I'd got this years ago.
