1. A collapsible stand for music amplifiers and the like, comprising a base having a pair of elongated laterally spaced, upstanding side members each having a bottom edge portion formed with a raised central section extending over a major portion of said bottom edge portions and thus adapted to form gaps between a stage floor and said bottom edge portions and to form a pair of downwardly extending front legs and a pair of shorter downwardly extending rear legs, a forward substantially planar platform having lateral ends connected to said side members and being slanted downwardly from front to rear at an angle to horizontal of up to to about 45°, a rearward spanner member having lateral ends connected to said side members, wherein said platform is spaced vertically above said front legs to provide an open space which is in communication with said gaps, a back rest pivotally mounted on said side members for being pivoted from a stored position adjacent a top of said platform to an open operative position at substantially 90° to said top said back rest having said side members affixed to opposite ends of a laterally extending back piece, the pivotal mounting structure for said back rest comprising side supports affixed to opposite ends of a laterally extending portion of said back rest wherein each support is pivotally mounted on an adjacent side member, cooperating stop shoulder means on said spanner member and on said back rest for positioning said back rest in said open operative position, and wherein all floor contacting leg portions terminate in a laterally extending ridge of substantially zero contact floor surface whereby interfering sound waves and structural vibrations generated and transmitted between an amplifier resting on said platform, the present stand and a stage floor, are markedly reduced, wherein said stop shoulder means on said spanner member is on a lateral top surface thereof and wherein said stop shoulder means on said back rest is on a lower edge portion of said back piece, wherein said top surface of said spanner member lies in a plane which is below said lower edge portion of said back piece when said back rest is in said open operative position, whereby when said back rest is pivoted forwardly and downwardly with said back piece positioned against said top of said platform the exposed upper surfaces of said back piece and said spanner member lie substantially in a common plane, wherein an item support shelf extends between and is affixed to said side members and is spaced below said platform and extends from the front of said base toward the rear of the base to provide a storage area, wherein said storage area has an access opening at the front of said base, wherein a closure panel is pivotally mounted to and at the front lower portions of said base sides for allowing said panel to pivot up or down, and wherein shoulder means is provided on an inside surface of said panel for supporting a musical instrument in a generally upright posture when said panel is in its open posture. 2. The stand of claim 1 wherein a toe hold shoulder is formed into an upper portion of said panel to allow a person to open down said panel with the toe of his or her shoe. 3. A kit for supporting music amplifiers and the like, said kit comprising a collapsible stand having a base having a pair of elongated laterally spaced, upstanding side members each having a bottom edge portion formed with a raised central section extending over a major portion of said bottom edge portions and thus adapted to form gaps between a stage floor and said bottom edge portions and to form a pair of downwardly extending front legs and a pair of shorter downwardly extending rear legs, a forward substantially planar platform having lateral ends connected to said side members and being slanted downwardly from front to rear at an angle to horizontal of up to to about 45°, a rearward spanner member having lateral ends connected to said side members, wherein said platform is spaced vertically above said front legs to provide an open space which is in communication with said gaps, a back rest pivotally mounted on said side members for being pivoted from a stored position adjacent a top of said platform to an open operative position at substantially 90° to said top, the pivotal mounting structure for said back rest comprising side support members affixed to opposite ends of a laterally extending portion of said back rest wherein each support member is pivotally mounted on an adjacent side member, cooperating stop shoulder means on said spanner member and on said back rest for positioning said back rest in said open operative position, and wherein all floor contacting leg portions terminate in a laterally extending ridge of substantially zero contact floor surface whereby interfering sound waves and structural vibrations generated and transmitted between an amplifier resting on said platform, the present stand and a stage floor, are markedly reduced, wherein said top surface of said spanner member lies in a plane which is below said lower edge portion of said back piece when said back rest is in said open operative position, whereby when said back rest is pivoted forwardly and downwardly with said back piece positioned against said top of said platform the exposed upper surfaces of said back piece and said spanner member lie substantially in a common plane, wherein an item support shelf extends between and is affixed to said side members and is spaced below said platform and extends from the front of said base toward the rear of the base to provide a storage area, wherein said area has an access opening at the front of said base, wherein a closure panel is pivotally mounted to and at the front lower portions of said base sides for allowing said panel to pivot up or down, and wherein shoulder means is provided on an inside surface of said panel for supporting a musical instrument in a generally upright posture when said panel is in its open posture, and wherein a toe hold shoulder is formed into an upper portion of said panel to allow a person to open down said panel with the toe of his or her shoe. 4. The kit of claim 3 wherein a table top structure is provided and comprises a substantially flat upper surfaced support member extending between and affixed at lateral ends thereof to a pair of opposing side members which, in elevation, are wedge shaped with the rear of each side member being higher than the front by the degree of the angle of slant of said platform whereby the upper surface of said support member is substantially horizontal. 5. The kit of claim 4 wherein said table top structure is stored within said storage area.
