Mark III foot switches compatibility

[mindbenderzzz]

how compatible are the foot switches being offered for others mesa or even something after market from other brands.
im about to acquire a Mark III with no foot switches are they amp specific or are they compatible. I see that most Mark IIIs have a few switches for a few different things and hoping to get an an all in one. i noticed there is one for a Mark V that has everything i need all on one pedal was wondering if it was item specific or could i just plug into a Mark III and be good to go.
If not this what are some other good options

I use a leftover footswitch from a fender Blues Junior. It's just a single DPDT switch wired to a standard TS cable. Works perfectly

I believe Mesa will have the originals in stock from time to time, just have to check every so often (just bought one myself not too long ago).

Another option is the aftermarket all in one from Switch Doctor. I have never used it but was contemplating one.
