Modding EH Big muff, Small Stone & Dunlop Crybaby for T/

[Kai]

i have been thinking of modding these pedals for the past month now to make them true bypass, from what i understand i need 2 3PDT toggle switches and a DPDT  toggle switch for the crybaby...

do i need anything else or is that it?

Also, i am not exactly sure where to put these switches in the circuits (i'm not very good with electronics but i have some one to give me a hand )

is there any other cool crazy sounding mod's that can be done?
I play alt.rock/grunge type music (Think Smashing Pumpkins crossed with SoundGarden)

Anyways, if any one could help i would be very greatful!

Thanks

Kai
