I discovered this item several years ago when my wife was doubling on hand percussions while singing for a band. I wound up buying one for my music stand for convenient access to a tuner and other accessories. It seems like a great place to keep your preamp without having to reach behind you to tweak your amp’s EQ or, more importantly, volume knob for down time or in between sets. Just want to share it with my DB brethren. It’s made by Rhythm Tech.
