jacks and switches!?

[gizzi]

i have some questions about jacks... first of all, what is the standard size dc jack for a 9 volt pedal? (2.5 mm, 2.1 mm? or what?)and what are the three lugs functions? also, where can i buy PC mount 1/4 inch jacks with metal threading? (for any of you who have taken apart any of the recent marshall pedals, they have jacks that run flush with the casing on the inside and and on the outside the nut screws into it...is there any where that sells these kind of jacks?) i'm also wondering where i can find PC mount DPDT footswitches (the carling style ones). thanks a lot, garrett

2.1mm is standard.

The three lugs are for +,-, and the third is connected to either the + or - pin (closed when the jack is unplugged and open when the jack is plugged in). The allows you to bypass the battery when plugged in.

Mouser should have the 1/4" jack you're looking for.
