Get a propper 9vDC power supply without hum. Do not buy a cheap one!!! You can connect both pedals two it using a so-callled daisy-chain cable.
Note: each pedal has a maximum current that is mentioned on the pedal somewhere. Also, the supply has a max current it can deliver.all pedals attached to the supply must not have higher combined current than the supply can deliver!
