Reminds me of EBS amps; if you use a specific guitar lead that they make, the amp can power their pedals through the output jack, pretty neat.

This is awesome. I want this. I bet you're fucked if the pedals are different polarity though (which obviously they won't do with their own pedals).

Have you guys heard about the Nano Clone and Nano Muff? They can't be daisy chained powered with other pedals as they're positive ground and ground out the power supply through the TRS jack connections with the other pedals. You have to use an individual Wall Wart for them or battery power them.

Damn. It is pretty stupid in this day and age to make a positive ground pedal.

It's quite funny - they're coming off all "It's not a flaw it's a design decision!" on the HCFX forum. As far as I can remember, only the FuzzFace is +ve ground and that's so you can use PNPs...

Couldn't you just switch around the wires to the power jack inside the pedal? Neutral I'm not sure exactly what you mean..

No, unfortunately that makes the Nano Clone... not work. It's not supply polarity that's the problem, the problem is that positive ground is when the positive (live) terminal is connected to the chassis, it is the ground point rather than zero volts. It makes it incompatible with other pedals on the same power supply as it grounds out the power.

Pft. They can say whatever they want. It it completely possible to use neg ground with PNP transistors also, you just have to design it right. I honestly cannot fathom a true technical reason to "decide" on positive ground.

It won't have been an original FF design then.

It's a crappy excuse.

You weren't very specific then. You said "Fuzz Faces."
