Up for sale is a 6U 90HP powered Monorocket case in purple Tolex. The case was purchased used from the original owner in 2014. It has since been with me and spent all of its time in my smoke-free home studio (no gigging). It has been out of use since I upgraded to a much larger case in 2017, but it still works perfectly. It is in great cosmetic condition, with a few mild abrasions on the hardware–specifically the hex bolts on the butterfly latches. The Tolex comes up short along the surrounding edges by a fraction of a millimeter (it looks like the manufacturer was really cutting it close, but this seems to be common in Monorocket cases from the same era). That being said, I never had a problem with the material lifting. There's plenty of juice in the unit to power anything you can fit inside, and the top power rail provides 5V. The mounting rails feature sliding nuts. It comes with a power cable and a bag of 4-40 screws.
Local pickup is available in Austin, TX and the surrounding area.
