Seriously, I'd just like to minimise the space taken by the two power supplies and only use one long main lead to power them instead of two long ones that'd require two wall sockets.
The pedal that I would use one of the power supplies for is a Boomerang III looper.
According to the info on this page (the "Power Supply Info" tab), it could work with a daisy chained, non-isolated supply under certain conditions but I don't know if the 1-Spot I have would be able to handle the load.

I used the converter included with the 1-Spot package to change the polarity of one of the connectors.
I then tried the Boomerang on its own and it worked fine.
I then plugged another pedal, a Joyo American Sound and it was still working.
Next came a Joyo Vintage Drive, then a Joyo Digital Delay and all still seemed to be ok.
I then decided to go for broke and plugged a Zoom G3X and guess what...
All the pedals were doing their jobs without a hitch.
Maybe I do not need a second power-supply after all.

Q. What are the power requirements for the RangTM III and Chorus*Delay?
A. The E-Series pedals are very forgiving and will work with many types of power supplies. Most supplies with the one of the following output specifications will work:
Always OK
1) 9VAC, 500 to 1000mA
2) 9VDC positive tip, 500 to 1000mA
Usually OK *
3) 9VDC negative tip, 500 to 1000mA
* If your DC supply is ISOLATED the polarity of the plug doesn't matter (can be either + centered or - centered). If the supply is not isolated (either directly or through other pedals which may be connecting one side of the supply to the audio common) you must use a + center plug.
* In order to provide for some flexibility in power sources for the E-Series pedals, the power jack is NOT connected directly to the audio signal ground but is routed through a full-wave bridge rectifier prior to a connection to all internal circuitry. This approach allows for the use of AC power sources and auto-sensing of DC power sources but mandates that the power source MUST BE FULLY ISOLATED from any direct or indirect path to the ground side of any audio/control inputs or outputs connected to the pedal. A direct path could be created by using a power supply that uses a 3-wire mains plug and has one side of the output connected to the mains ground (rare). An indirect connection can occur when a single power source is 'daisy chained' between several pedals and one or more of the additional pedals has its audio ground connected directly to one side of its power jack (common). In this case one wire in the power cable attached to the E-Series pedal is indirectly connected to the audio signal ground and this violates the full isolation requirement. This situation cannot only create a 'ground loop' hum problem but could also severely damage the power supply and/or the E-Series pedals. In general it is recommended that the E-Series pedals always be powered with the power adapter supplied with each unit. Boomerang Musical Products, Ltd. cannot be held responsible for any damages which result from the use of any power source other than the one supplied with each unit by BMP.
