You can use any footswitch you want, as long as it's compatible. Just go to the shop and bring your amp (if they don't sell it there) and ask to try a few ones out, take which you like the most. Alternatively if you know the exact model footswitch you can ask specifically on forums, that's basically it.

Boss FS-6. I have one, and I love it.
