In a previous video I covered how noise can be passed between effects pedals when using a daisy chain power supply. Several people complained it was not a fair test because I used a battery for the isolated supply. But does it really make a difference to this issue?
In this video I redo some of the tests, and we measure and listen to the results to see if there is any difference. As before, after the tests we explain the reasons behind why we got these results.
