problem with 3dpt

hi!
first of all, I am really new in this, so don't mind my lack of basic knowledge..

I have a problem with 3dpt, I can't find it anywhere! I live in Belgrade, Serbia, and here they have no idea when I ask them about 3dpt in stores, most of them never hear of it, and at the moment I can't order it online or anything (long story).

Is there a way to build the pedal with SPDT and something else?

You could build it with a DPDT if you're prepared to omit the LED, or using a SPDT you could either use it to pull in a separate DPDT relay (or 3PDT if you can find them to give you the LED capability back), or as a last resort you could use the horrible switching that MXR uses which will mean your input will always be connected and you switch the output.

well,
how do I connect spdt with DPDT relay?

that seem like a good option, I thought of that, but I don't know how to do it...

Just take one side of the relay coil through the contact on the stomp switch. So when the contact is made it completes the relay coil circuit

I understand that part, but I'm really a noob,
is there a chance you can explain me on a loop box (http://www.generalguitargadgets.com/ind ... &Itemid=26) for example, If it's not a big deal...
it is a simple project, so I could understand the process, I don't know how relay works..
