I got a switcher from LoopMaster and it I really like it. Mine is just an eight effect pedal switcher (eight loops, each one with a toggle for on/off and an LED) but they can build you just about whatever you might need. Mine has a master on/off, a tuner out, and then eight pedal loops. The tuner toggle silents the entire rig (unless you have an OBEL) and the unit is true bypass. Each pedal grounds out when bypassed so there is no leakage. It is passive and dead silent. You can order it with or without LED's (I color coded mine to my effects, blue is MU-III, yellow is Dist+, amber is Phase 100 and so on) and the LED's add no noise whatsoever. As the unit is true bypass you need to either have a buffer in your guitar or a buffer pedal before the switcher to avoid signal degradation down the line
Mine took about six weeks to build but since then Mark (I think that is his name) who runs the business hired some help and they are getting the units out in about two weeks, The units do not have the midi-capable flexibility of Voodoo Labs GCX/Ground Control units, for example, but for a low cost, high quality switcher, the LoppMaster nails it. The audio quality of my signal path increased dramatically when I got the switcher. And when I say dramatically I mean night and day.
