Thanks for all the info.
The one thing I haven't received a response about is the power passthrough on the tuners and what it takes to make it work. I like the idea of being able to save one of the power outs on a PSU for a real pedal instead of wasting it on a tuner. I've seen multiple connection power daisy chains, but are there some that are just one to go from the tuner to another pedal?
I've used the power out on a 1st gen Peterson Strobostomp to run a VT Bass and it worked great. All you need is the cable to jump the two pedals and those are cheap and readily available. Any pedal that's pretty vanilla in its power requirements (9v/100mA/-pin) that's sitting next to your tuner is going to work just fine. Try it.
