###SORTED!!### Help from the electronics/wiring experts required please #1
This footswitch connects to the back of an amp via a 'stereo' TIP/RING/SLEEVE ¼” jackplug:  Both switches work independently of each other: - The Channel button toggles between the amp's 'Rhythm' channel and the 'Lead' channel
- The Boost button toggles a crunch boost to the Rhythm channel
I think I have all the components here to knock up my own version (actually two separate footswitches), but I just need to check with the experts here before I blow something up. I have two simple on/off footswitches I made ages ago and a stereo jack plug. The vague memory I have of A-Level Physics leads me to think that either (or maybe both) of these wiring jobs will work. If not, does anyone know how to wire up the components correctly? Please excuse the crudity of my DIY Photoshop circuit diagrams...   Any advice would be most gratefully received

I had one of those I took apart to make a Ventilator (rotary speaker emulator) speed switch.
I think the original Fender scheme used some resistor logic to do the switching, according to a schematic I saw.
try to go to Fenders site and scope out the schematic for the amp in question and see how the original switches are configured, I am thinking it is a little more than simple spst momentary switching

Both your diagrams are the same. It matters not which way you choose to connect the green. The important thing is, do youhave the correct switches??  are they push on / push off or momentary? Which does the amp need?

Ground will go to the common end of both switches the 'on-off' signal ends go to tip and ring. On most British amps I've seem they work that way given the swithes are just alternate on-off ones as in your diagam. Of course I may be completely wrong on this particular amp. But for £12 as per Marks suggestion that would likely be cheaper than the parts.

The switches have to latch once they are pressed, not momentary. Steve I found from a bit of research the wiring diagrams can be more complex than you are suggesting especially with LED's involved etc.
I have got a Marshall Valve State amp here in my studio and it does not have the footswitch. While attempting to buy one I came across the circuit diagram. It was not what I expected. See if you can get onto the circuit diagram for that particular footswitch. Amp schematics will probably include it somewhere. Be careful what you are shorting out.
I have the parts here to make one and will wire it up when I have got time. Many may use the circuits you have shown but this Marshall footswitch had a quite a lot more going on.

I think you should endeavor to get some specific info for the amp.
It could require one of a few different setups... as Karyn has suggested above.
What model amp is it?
best regards,
mike

Thanks folks  Karyn/JB - the units I made have identical 'standard' on/off footswitch buttons to those on the Peavey unit I pictured. I used them previously to turn GearBox/Pod Farm effects on and off with my Line 6 UX2.

You could use an Ohm meter to read from ground to each ring. This will tell you whether the switches are opened or closed when engaged or not engaged.

Get a wiring diagram from Peavey for the specific amp. I've found 3 different versions of Peavey 2 way switches so far. Is there a spec in the manual?? Peavey will give you one.....oooerr missus.

Bad news... they all look exactly the same, but work very differently. If the amp uses FET switching internally (most likely) then it'll need momentary switches and maybe a resistor or two... Momentary switch, put yer foot on it and it closes, take yer foot off and it opens. Saw a band a couple of weeks ago where the singer had made his own foot switch to turn the vocal echo on/off. He had to stamp on it twice every time because he'd used latching (push on/push off) switch instead of momentary.

Here is what you want..  Use standardpush on / push off switches You can ignore the LEDs if you want.

first Idea will be your easiest depending on the cable you have (if its 3 wire, just add your jumper from switch 1 to switch 2 for your ground/common wire) Other than that you are on the money. If you have 4 wire you can do idea 2 but no sense in it really. Why run series parallel all the way back to the TRS jack when you can complete each circuit right in the foot switch.
