The Mastermind GT has four rubber feet that are screwed into the case. You can easily remove these if you want to mount the GT to a pedalboard. Once the feet are removed, the bottom is completely flat, so Velcro or Dual-lock can be used. Also, you can use screws to mount to a board. There are four threaded holes (8-32 American thread) where the rubber feet are secured, and these can be used for mounting.
