I have an alternative “work around” solution that may not be exactly what you were thinking of, but it can still keep things “neat” with a couple of cable ties… I’m assuming that the overall goal here is ease of workflow - so you can just plug the whole pedalboard into 1 mains outlet, audio out into your amp (or whatever) and start playing ASAP without needing to worry about plugging any extra things in.
If your mainstay pedal power supply uses a size C13 IEC power plug like mine you can use this solution (I’m currently using a GigRig Generator).
You might have noticed that the Analog Drive’s power supply uses a size C7 (figure 8) IEC plug. Different size plug - but IEC all the same…
Well, you can easily buy online (on Ebay or otherwise) a Y-splitter cable that splits your C13 IEC to both one C13 plug and one C7 plug. (A simple google search for it will give you multiple results).
This way power can go to both your normal power supply and also to the Elektron power supply… You can plug it all in and permanently tie it all up neatly (including the Elektron Supply) with cable ties underneath your pedalboard and therefore still manage to have only one cord leading from your pedalboard to the nearest mains supply.
If it’s all underneath no-one will be the wiser and it all remains neat and tidy if you do it right!
