Help. I'm a stomp box pedal newb. The coronavirus has taken it's toll on my sanity and credit card balance. Bought some pedals, a pedal board, and a True Tone 1 Spot Combo to power it. Pedals in order of appearance in to out. KLIQ Tiny Tune MXR Phase 90 Boss BD-2 Mosky B-Box Ditto Except for the KLIQ and Ditto, they all make humming noise when daisy chained (correct term I think) with the 1 Spot Combo. Using the same power supply, they hum a tune if plugged individually. Also, turned off LED lights with dimmer switches and unplugged TV. No change in noise level. I think it's my choice of power supply. Remember I'm a newb and afflicted with the "I've been home too long blues". Are they out of order? Or is it, as I suspect, primarily the power supply? Can anyone recommend better power supply that should correct my above white noise humming?
