I only know of one performer that used the Rock & Roller shelf--he loved it! He was primarily doing NH jobs, often three in the same day on different floors of the same facility. He had a pair of speakers on the bottom and his keyboard on the shelf. Most of the time he left the entire rig assembled, strapped everything down with heavy, rubber bungee cords, and at the end of the day, rolled it up a ramp and strapped it securely to inside of his cargo van. His setup time amounted to next to nothing. He rolled the rig out of the van, in the door, removed his mic from a small drawer, plugged in the main extension cord, fired up the system and went to work. For someone that is primarily using small speakers and working the smaller NH gigs, this is a great setup.

Good Luck,

Gary
