Can anyone tell me the power and voltage requirements for the Demeter Tremulator and Prescription Experience pedal? I'm having a custom power supply made and I can't find any info regarding these requirements. Any help is greatly appreciated.

Why custom?

I need a custom power supply because I have several units From DMC and Axess electronics which I also need powered. I've got about a dozen units to power and I'd like to have one box to do it all.

Demeter is standard 9vdc but uses a US spec 3.5mm tip positive connector.

Just contact each manufacturer with your question about their product's power requirement, I did this when I needed to know current draw and which were tip or center positive. Most will answer you without problem on this.

I tried contacting both manufacturers, but they never responded back to me.

Spenceroo,

This doesn't do any good to their customer service reputation...

This is really frustrating for you I'm sure.
Keep digging, wish you best of luck on this.

I would like to thank Tom Knesel for his help with my situation. He's the kind of guy we need in this business to help keep us [and him] going. Tom, we need more people like you! Once again, thank you.
