What about the Echo in the FX loop?? Also, which output do you use on the Echo??
About the power and so..... Just buy a dencent flightcase and build a pedalboard into that. I just got a Showmaster 48 flightcase that is big and sturdy enough to house all my pedals.
Because I build the pedalboard myself, I can leave space under the boards for excess power-cables. There is also a small box in the flightcase for the PSU
Output for a tuner is great and to my ears always needed.
