Here's the one I bought/use: https://www.amazon.com/gp/product/B000VXKUL0/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1

So, did a bit of looking, and looks like fender uses a different circuit layout to the katana. Almost certainly would not hurt anything, but probably will not work. https://www.thegearpage.net/board/index.php?threads/making-a-fender-2-button-footswitch.2190871/

If its a latching switch (not momentary) and uses a single TRS (3-conductor) cable, it should work. I bought a generic one that looks very similar.

Also, once old reddit goes tits up, thats when you will see a TON more migrations over here.
