I recently picked up a GK 1001 RBII and a GK RBH 4x10 cab... Great sound! One practical problem... I want to use the cab in the tilt back position but still have the head on top of the cab... it slides off because there is nothing holding it in place. I am thinking of a few solutions... 1) Velcro? I don't know if this will work or not. 2) The underside of the head has holes for screws already drilled in it. I am assuming for rack mounting or some such. I am thinking using "L" brackets of some sort to go on the bottom of the head and hook on the edge of the tilted back cab. Does that make sense? Other solutions?
