Gary,
Nice, clean lines, BUT......
(there's always a but)
There are two potential "hum-hazzards" in your design.

1) the power cord may cause hum because it is in a tight proximity to the line(signal) cords going into the amp. Usually, it's best to have power cords cross signal cords at a diagnal angle. If there is no hum .... no problem, but that raises a red flag in my mind from past experience.

2) the power transformers are very close to the Digitech, and sometimes, digital gear generates noise when close to transformers. Again - this is from past problems, and is not a hard rule.

If you get noise ...... check those 2 areas first. Other than that - it's a beautiful rig. Take it out and show it off with pride !
