Open it up. If there are 6 connectors on the footswitch then you need a DPDT one (google it, it's a fairly common part). If there are 9 connectors (possibly this one, as it's true bypass) then it's a 3PDT footswitch.
Hotrox have the 3PDT for just under £5 [url="http://www.hotroxuk.com/3pdt-foot-switch-11232-0.html"]here[/url], or a DPDT (double throw double pole) looks like that, but with only 6 connectors. If you can't find a DPDT then you can simply use a 3DPT and only use 6 of the lugs.
Hope this helps, Paul
