I'm interested in making an expression pedal and a footswitch for my zoom g2, mostly to get more comfortable with DIY but i also need them

How would i go about doing this - can i just find the schematics for any old footswitch or does it have to be a specific one because I can't seem to find it?

Can someone give me a rough idea of how much it will cost?

As a broke mother ****er would i just be better of having a go at making my own wahwah instead of bothering about the expression pedal?

The footswitch for the G2 is Non-latching if that helps...

Expression Pedals are all wired the same way, tip - Lug 1 of pot, band Lug 2, ground, lug 3.
