Have you ever looked inside an FC-7 Roland pedal Donny? Does the FS-5/6 have the same surface mounted switch mechanism?

I've been using an FC-7 for all my switching needs, including sustain for three years now, and I have reliability problems on the switches I use for sustain (not the rest), probably because the thing wasn't really designed to be used for something you do thousands of times more than change variations, start and stop, etc..

If the FS5/6 has a different switch mechanism (it has an identical exterior) to the FC-7, maybe I can replace the FC-7's switches with these more reliable ones (presumable, they ARE more reliable? You use them for sustain?)...

Any advice would be appreciated.
