Powering multiple Boss pedals.

Powering multiple Boss pedals.
I have a Boss TU-2 Tuner pedal and it can power multiple Boss pedals, I know that using the same power source to feed multiple pedals can sometimes cause noise issues like ground loops but I was wondering if the Boss pedals are designed to be powered with this daisy chain scheme and not present any noise problems.  
I'm betting that Boss has this all sorted out, am I right?

I am a Roland repair tech, and I can tell you that daisy chaining Boss pedals is OK, as long as you use a Boss PSA-120 adapter, and don't exceed the current limitation of the adapter. Check your individual Boss pedal owners manuals for current draw of each unit in the power chain. Boss PSA-120 is rated for 200 mA. As long as your pedal chain does not exceed 200ma you are ok.
