Switching, switch board.

Jsh	Switching, switch board. First of all thanks to Yang for giving me this link. I hate to tapdance on stage to switch my stompboxes, so this leads me to making my own switching board I am working on that switching board. I want to make 6 loops for 6 groups/Units of FX's. I don't know how the Boss FET-switching works , but it leaks the wet sound in your dry signal. My SD1 for example gives slight distorted FX when it is not activated; in other words it leaks sound. I first thought the FET-switching was a cheaper way to build a multiple switch board, but 1) I can't find a description (schematic) of it and 2) It leaks. So to the point. I made a schematic using relays. But I have some questions: 1) What are the bad sides of Relays for switching (besides the costs, of course) 2) Is there a better way to make it possible to switch 6 FX-stompboxes using one board of switches? Any schematics around? 3) How do those (Midi-)Patchers do the switching? 4) Can it be done with simple IC's? 5) Do I have to switch the (-) earth too when switching a FX or is the (+) enough? [this is respect to the possible 'POP' in the switching and possible the earth-loop] I will draw my schematic and post it here later today. As you will see, I 've tried to make it flexible and "programmable".
