so i'm trying to decided how many 18v twin cable things to order for my pedal power 2 plus.

here are the pedals in question.

-fulltone fulldrive 2 mosfet
-fulltone ocd
-homebrew electronics frostbite flanger
-diamond memory lane 2

i ask because i know some of these pedals, while 18v, still need more than just an 18v split cable. ex, reverse polarity, and some other stuff that i don't really understand.

can anyone help me on this?

oh and one more thing. i have a 535q dunlop wah. i'm pretty sure it says its 9v on the thing. but i've read that its actually 18v? are there two versions?

The OCD and Fulldrive 2 can each be powered at 18V using our 18V Y cable connected to any two Pedal Power 2+ outputs set to Normal. The Memory Lane can be powered using EDIT: a Reverse Polarity 18V Y cable but requires using outputs 5 and 6 with the switches set to Normal. The Frostbite will require a reverse polarity 18V Y cable and can be powered using any two outputs set to Normal.

You would be using all eight Pedal Power 2+ outputs with four 18V pedals connected this way. It can be done, but unless you are willing to run one of the Fulltone pedals at 9-12V, there will be no room for the 535Q. There are two versions of the 535Q, if yours says its 9V, then 9V it is.

thanks alot for the in depth help.

ok, are you sure the memory lane can be powered using the 18v y cable? or is it the 18v reverse polarity y cable

Would you look at that... it is Center Positive. You are correct, and the Memory Lane will require a Reverse Polarity 18V Y Cable.

I power my 18v 535q with the 4th channel of the Pedal Power 2 dip switch normal. That channel, according to pedalpower, is a 9v 100mA channel. It works fine. Never Had a problem.
I Also power the electro harmonix HOG with the 5 or 6 switch up. Works fine! Both!! NEVER had a problem!
