Wah pedal power supply pedal power 2 issues

[Colin]

Hi - I'm looking for some help with my pedal board in particular for powering my slash wah cry baby. I'm using a pedal power 2 plus and via channels 5 and 6 using a voltage doubler cable ppeh24 to give me the 18v required to power the wah - is this the way to do it? I seem to get no power but the pedals good as I can power it via 2 x 9volt battery's ok. Could do with some advice please,

Cheers
Colin

No... that cable (part# PPEH24) is the wrong polarity (it's center positive).

What is needed is the standard polarity model: Voltage Doubler Cable (standard polarity, 2.1mm), part# PPY

Cheers!
