EHX Micro Synth power supply?

In the manual for the Micro Synth it says the 9.6v power supply must be used with it, and then later states that it simply will not work if used in some kind of daisy chain with other pedals. I've seen plenty of manufacturers say the first bit, but the second bit seems odd. I've not tried it, anyway, just in case it blows up or kills my dog or something. What would cause it to not work with a daisy chain? And what's with the 9.6v? Every other pedal I have is just 9v, although I have seen a few 9.6v Boss transformers before, I think.

it'll work, they're just washing their hands of the matter.

I have the XO version of the Micro Synth, and they even went so far as to put a sticker above the jack that says "DO NOT DAISY CHAIN."

It can confirm it works fine with the supplied 9.6V EHX supply, a standard Boss supply, and the Voodoo Labs PP2+.

Yeah, I have the XO, it was secondhand so no sticker, though.

I'm concerned that the POG2 might be un-daisy chainable too, now. One of the minor reasons I wanted to upgrade to the newer version was because it was now a 9v pedal and I would be able to daisy chain it.

Poop.

Another thing I've been wondering is the current draw for some pedals. The Ring Thing apparently draws something like 170ma, while the power supply I have recommends that each individual daisychained effect should not exceed more than 80ma. Is this just a general guideline, or will the Ring Thing just not be able to draw the power it needs through the daisy chain? I can't see how, but I'm not exactly an expert on this stuff. I've only ever used batteries or daisychained mini dano pedals, most of which have a draw of something like 5ma at most.

I hunted into the darkest corners of the web and the only information I could find regarding Micro Synths and current draw was a guy on the EHX forum making an unsourced comment about how EHX says it draws 180mA, and some old useless information about the draw of the non-XO versions, which were a completely different 24V beast.

I also have a POG2 (slightly outdated board here), and everything works just fine when using the PP2+ power supply. I guess that doesn't really help though, because the PP2+ has isolated outs. The EHX page with the POG2 instructions states that it draws 180mA, so that probably won't work with your power supply either.

As long you don't exceed the total capacity of the adapter, you'll be okay. It's probably not a bad idea to leave about a 5-10% gap between the capacity and your total draw, just so you're not slamming the thing full on all the time.

Here's some more good information on the subject.

That's an awesome pedalboard you've got there, and a good link, too. So basically, as long as I'm not hammering my Powerall/Godlyke whatever, then it should be alright?

Also, off-topic, but did your Micro Synth come with rubber feet?

Thanks. I've since replaced the EQ with an EHX Germanium OD, which has turned out to be awesome.

And yeah, I would recommend just adding up the draw of each of the pedals to see what you've got. (Here's a nice list of popular pedals and their power requirements, from the same guy I linked earlier.) That 5-10% margin is just a personal guideline, but I figure it's a Good Thing to leave a little room there so as not to completely exhaust the tiny mice running on wheels inside the power supply.

This pretty much the exact scenario is actually what led to me buying that Pedaltrain board and the mating PP2+ power supply to mount underneath. I was just tired of dicking around with a bunch of adapters and batteries, and I did some investigation into things like the One Spot, Godlyke, and others, but I didn't find a suitable solution.

Yeah, but I took them off in favor of the super-Velcro to affix it to the board.
