If you have a faceplate you can mark the slots on the box and then just cut a larger square hole in the box, the faceplate will cover the hole and you will only see the slots in the faceplate.
You can always use your own slide switch for the ground lift if you want, or just carefully file the hole into a slot, its your pedal so just modify away all you like.

Thanks Tassie. We think alike.

I considered the faceplate thing you suggested, but worry that the slotted plastic faceplate over a big hole with hot valves underneath might not hold up. Probably worrying for nothing, I'll think about that some more.

I've just ordered some cheap 3mm cutters for my trim router, I'll try slotting the aluminium over the existing holes first and see what that leaves me with.

Very minor issues. For my next one (!!?) I'll drill the enclosure myself. Pray for me..
