Ordered one of those pumps for my TC Nova Repeater so I can use 1spot to power my entire pedalboard (8 pedals in total, iso pump only to go for Nova Repeater).

Is it basically an isolated output? Description seems to say so.
Any noise issues?
I hope it's the same thing as using Repeater's dedicated PS without lugging a second PS around.

It is an isolated output. The one thing to consider is whether it passes enough current for your pedal. IIRC it only does around 200-300 mA.

At 12v it handles up to 480ma, more than enought for any of the TC Nova series.

BTW, I use a couple of the gigrig supa-nova offerings that do a similar thing and are designed specifically for the TC Nova pedals but are fixed at 12v. As much as I like gigrig products, I would have gone with the iso pump had they been available at the time.

Awesome! Thanks everyone! And yea I've already checked out all the specs, I know it has enough juice at 12V for any Nova pedal (they need 300mA) :)

The issue is when the ISO pump is putting out 300 mA at 12 volts, it is drawing more than 300mA from the 9 volt side of the 1spot. I don't know how to figure it exactly (it's not a transformer since this is DC...) but I would conservatively estimate it is drawing around 500 mA from the 1spot. Make sure the rest of your pedals can work with that.

Yup thought of that too, most of my pedals are analog and my current draw is probably less than 500mA from the rest of the pedals. My other biggest spender is ditto looper which is like 100mA. All other pedals are mostly under and around 20mA.

My old thread resurrection.
Lately, last couple of gigs I had a hiss noise coming out of the PA (when I had to go through PA). I thought it might have been my amp DI or bad power in the venues, since it really didn't come noticeable through my rig at all (and it's a big one - 412 cab, and a pretty cranked up amp). Today I decided to test out my pedalboard at home and noticed it hisses quite a bit when I plug straight to my computer. So off I went, testing pedal by pedal and the ISO pump seemed to be the culprit. It produced the hiss, as soon as I removed it and plugged my Nova Repeater without it (9V though), no more hiss.
Looks like my ISO pump hit the bucket, so I'll either have to go 9V daisy chained or drag the Repeater power supply (don't really like this idea) just for my delay..
Ya know, for $30 the ISO is going for, I'm not gonna bother replacing them every time they start introducing noise. I guess I got a bit over 2 years out of this one.

Did a test at home through an amp with my board, tried the 1spot daisy chained Repeater and then tried it with its own power supply on 12V. Much better signal coming through when it's on its own supply. I feel I get a bit of signal degradation if I chain it even when it's off (probably not a surprise since it doesn't have analog dry through, that's my guess). I'll definitely keep it on its own supply, much clearer tone coming this way, and less noise.

Another test - the iso pump works fine when I don't daisy chain it with other pedals, the noise is introduced especially when there's fuzz in the chain, but other analog pedals add it as well. I'm positive I didn't have this problem when I started using it over 2 years ago, and I haven't changed up my board much either (I removed the boost pedal, removed the ditto looper and added an octaver). Not sure when the noise was introduced tbh, but since I noticed it like a month or so ago, I take it something did go wrong with the iso pump (I still had the same board the last time I had no noise issues through the PA).
It's really hard to pin point this stuff now, but from now on, my Repeater is getting its own isolated power supply, the difference is really much for the better.
