Finally got cabs for my head, but i lost a lot of gear in a business falling out (long story). I need to get the best budget-concious pedal power bank, specifically one that you know is isolated up the wazoo and quiet AF, as playing will all be within a couple foot of a million other electrical devices , PC, monitors, plug extensions all in a tiny room.

Aside form the usual 9v, I need at least one 12v out for my old Arion Stereo Analog delay, and an 18v out for a future old school MXR eq. An on-off switch would be nice too but its a nice to have rather than a need.

Basically can anyone recomend one that hits those beats?

Also if anyone is selling one in the UK that covers those bases let me know.

Thanks!

I suspect that you're going to get a thread of people saying that the one they have is great, but I got in there first, so...

Sounds like the MXR Iso-brick is what you want. Isolated outputs, 6 of them 9v, 2 of them18v, then 2 that are variable between 6v and 15v.

^that's pretty slick.

Ha!

I've got a Fender Engine Room LVL 8:

Does not have one of these though.

How many outputs do you need in total?

Isolated ground power supplies are so expensive. I've looked at building one using encapsulated DC-DC converter modules but those are expensive too. Mains-to-DC modules are cheap on Aliexpress but trying to find them with actual mounting holes in the PCB is a different matter.

Been digging a bit. Seems the Harley benton power bricks are the real deal at half the price.

Thanks for the suggestions chaps, both seem to be around 140 which is mire than i'd like to spend, if only because it means waiting longer to save up. The Harley Bentons seem to be a good mid budget option. There is cheaper on amazon but most seem to be glorified one-spots in a box.

That's interesting. I'm sure the last time I looked through HB ones weren't actually isolated, similar to the rest of the cheapo ones.

That would be great, if they were.

Admittedly I'm going off "bloke said so on a reddit thread" here. The one he mentioned was this'un:

Will do some more fact checking
