Running a 12v pedal off an 18v supply - voltage reducer cable?

Nope. You can supply a device with excess current but NOT excess voltage.

You could make one easily enough using an LM7812 voltage regulator - they can be had for pence.

I' have thought that it would be OK to use the 18v supply into the 12v pedal without any step down in voltage.

If its one of my pedals then 18V will blow it up, think that would be the case with most others.

A voltage regulator circuit or DC-DC converter is the only way

Hmm...with my soldering non-skils it would be anything but easy
