18V compatible?

[coachseeley]

Evening,
I only have (2) 18V outlets left on my CS12 - and I would prefer not to use another Y-splitter.

Can I safely run any of the following circuits at 18V? (I've added notes on my thoughts)

Pyrocumulus (ThorpyFX Fallout Cloud) - ThorpyFX website says their pedals are designed to be run at 9V
Guardian (ThorpyFX Peacekeeper) - Same note as above
Shrapnel (ThorpyFX Gunshot) - Same note as above, and this circuit uses a 9.1zener that I bet I would fry
Acrylic (Wampler Plexidrive) - Possible, but may require re-biasing the transistors???
Magnetron (Keeley MagEcho)
Spirit Box (EQD Ghost Echo) - potential to fry the Belton Brick???

Thanks.

Not to seem like a dick, but ain’t nobody here going to advise you to go against the manufacturer recommended voltages and risk you getting pissed that you fried your pedals. If the recommended is 9v it’s probably because the electros/diodes/ICs aren’t rated for 18v. Pretty sure getting a splitter is cheaper than replacing your pedals, why risk it?

I hear you, and agree. I figured the Thorpy pedals were out, and also read some folks run their reverb and delay pedals at higher voltages, and like it.
Thanks for the reply. My impatience led me to use a splitter (the 3rd on this board) and the isolation noise wasn’t bad at all. I guess problem solved. Appreciate the input.
