Oh wow when they showed the HX my helix makes that noise if it’s near the computer or usb is plugged in. But helix uses an IEC cord and its own power supply so not sure what I can do about that.
Power Supplies vs 1Spots...am I a sucker?

My only criticism about that video is, Jimmy Fallon is a dildo.

Yeah not sure why they still make them. Kinda weird. The PP3+ is an awesome PS. Never a single problem with it.

That's interesting. Weird how some pedals do it and others don't. I haven't used an 1-Spot in ages, certainly not with these digital pedals. Good to know. .

I played last night with one 1Spot on the Tonex One and the other powering the GLXD16+, the Mooer E7 and the TC Sentry. Worked very well, there still was a tiny wheeze with the sentry off, but nothing compared to running all the pedals on the 1Spot. The same wheeze I had with the Voodoo Labs PP2+. I have to test to see if that is on the tonex one when it is all by itself. Maybe the GLX16D+ needs to be on its own supply? I think I found the Helix FX loops slightly noisy enough to cause the whole thing on some tests before I had the Tonex and I think I read or watched some video showing the same issue. Whatever it is, this should work fine until my Cioks DC7 shows up

My Shure GLXD16+ says 9-12v 400mA. Is there any advantage to running at 12v or disadvantage to running at 9v?

TONEX PEDAL, NOT TONEX ONE
9-15V 400mA, NOT 9-12V
BASIC FAAAACTS
Sometimes higher voltages help with headroom but in this case it receives a wireless signal so it shouldn’t matter. Looking at the manual… it states max output 7.5Vp-p so 9V is fine, it’s just a matter of delivering ~3.6W and it has tolerance for up to 15V.

My experience is: some pedal combinations do work with a daisy chain, some don't. Meaning "work" in a sense of working quietly.
I recently made a small board with:
- Behringer CC-300 (analog)
- Boss PH-2 (analog, converted from ACA-style supply to PSA-style)
- Boss DD-7 (digital)
--> these run in a DIY-ish THC effects uC-controlled relay bypass loop (just one loop).
- in front of that loop I have a simple buffer, and after the relay loop there is a Korg Pitchblack (old version).
- all this runs into a higain amp
I can power these by a daisy-chain, as long as I use an old linearly regulated power supply (delivers up to 1200mA), PLUS a Joyo noise blocker directly after the linear supply.
Omitting the Joyo, there is some hum (loop in bypass), which gets annoying with higain and high volume.
Using a switchmode power supply plus Joyo still inhibits some noise (not hum). Need to check the Boss PSA-S version, which is said to be quiet.
Strangely enough, when I leave out the Boss phaser, I don't need that noise blocker i.o. to get rid of the hum when powered with the linear supply. Can't remember what happened, when I used the switchmode supply.
In fact, this Joyo noise blockers can help in many situations.
I once had a bigger board with a mix of analog and digital pedals in combination with a G-Lab GSC-2 relay loop switcher. That one has two isolated power supply sections built in. No matter what combination I stuck the pedals into those two sections, there was always some hum or noise (can't exactly remember). Once I put a Joyo noise blocker somewhere, things got quiet.
To get to my two points
1. According to my experience, it's difficult or impossible to predict what happens with a given setup
2. The Joyo noise blockers can help in many situations an cost next to nothing. They in fact are a chip based isolated switchmode power supply section. Basically something which would be built in a modern multi-power supply multiple times, but as a single unit in a very tiny enclosure.

I got the Decibel Eleven Hot Stone Deluxe to power up; a Decibel Eleven Loop to footpedals under MIDI control, a Boss GE-7 band Eq, a MXR Ten Band Eq, two Seymour Duncan SFX-01 Pickup Boosters, Arion Hot Watt 2, a EHX Ravish Sitar simulator pedal and a Behringer AM100 Acoustic Modeler
Two of the Power ports have a knob to let those ports power pedals between 5 to 9 volts and the transformer and osolated shielded power ports are 100 % quiet and clean.

Just for the records: I bought a Boss PS-230S and it works perfectly quiet with my setup described above, but does so even WITHOUT the Joyo noise blocker.
The switching wall wart style supply does not seem to be something special. But there is some kind of lump or bump in the cable, quite towards the end of it. You can unscrew it, and there is a small PCB inside with two toroidal chokes on it. Maybe this is the magic

I had this. Should have kept it.Never found anything better than my skb pedal board...with the included Furman SP-8. 20 years on, still kicking ass and quiet. 3 outlets 8 taps ...plus a stereo patch bay with stereo FX loops.......such a value. Plus it travels amazing!

Just saw one on CL for 40 USD...a newer one with wheels and a handle even!

Late to the party. Buy one of these:
www.thomann.co.uk
*ZERO* issues, plenty of outlets with mucho amperos, 3A output for modelers, USB A and C outlet for your tablet/phone.
Quite a brick but I love it. I'm running a GT-1000, a Stomp and several pedals of it. Yes, the Stomp needs a current doubler, but that's a non-issue.
My second HB PSU, first smaller one was on the main board (hence plenty of gigs and carrying) for 3 years and is still working on a smaller board. So that might be a good choice as well.

No nasty wallwarts for either of them, too.

I have a Voodoo Lab x8 or something like that, and I have current doublers for both the Friedman IR-X and HX Stomp, and I can power both plus some analog pedals. That works pretty well.
The One Spot is really impressive for the money. It has tons of power, like 500-600V. It can power a chain of analog pedals no problem. I wouldn't use it for any digital modelers, but if you want to save some cash, you could easily do a One Spot for a handful of analog pedals and a separate power supply for something like an HX Stomp or whatever.
