I've used a few of the SA pedals

...I might be able to help you out.
Easiest thing to do is to flip your pt mini the other way around. The pedals have enough clearance over the lip so that you can hit the switch with ease.
If you want to set them up in a more "traditional" orientation, most cables are going to take up about a half inch on the back, so that means your pedals will hang over the lip half an inch. Perfectly functional, but this can drive people's OCD crazy.
