There's not too much that can go wrong really, if the pedals are all expecting 9V and you have a PSU with a load of 9V outputs then you're pretty much in the clear. As Elf says, if in doubt just ask here.

Another bit...the 500mA rating is max draw...do you ever have a situation in which all your pedals are in use at the same time?

I have anywhere from 6 to 10 pedals in my board and it's rare that more than 4 are on at once so the max rating never really comes into play.

Also, fwiw I use a voodoo power 2 which allows me to alter voltage for two outputs and provides leads for non standard pedals. about $170 USD new, much less used.

Although lately I can hear it whine and I'll probably replace it soon, it has been through the wars for about 8 years now so I won't fault it for giving up the ghost.

Take my advice, I'm not using it.

The most I'll have on at a singe moment is may two of the gain pedals and the wah. The TU-3 would also be switched on when tuning, so thats a max of 4 pedals at once and that's probably going to be a very rare occurrence.

What about the buffered pedals like the TU-3? Will they always draw?

Yes, though I suspect most of the electronics will be active in the tuner all the time, you just won't be lighting any LEDs in bypass.

Ah! So from the sounds of that all will be well. Once payday hits, I'll get the Thomann one and plug in and test them one at a time.

Some of the reviews talk of a nasty hum... Does anyone know how bad that is? I'm not hugely fussed, and I can always upgrade later.

Any hum will be dependent on the pedals used and the severity of any ground loops created caused by not using a PSU with isolated outputs. This is normally far worse with digital pedals like delays and choruses than with distortions and drives. I doubt the PSU itself creates a hum.

True enough but, at the price, and for my needs it works a treat. YMMV :)

How about this as a halfway house? https://www.thomann.de/gb/harley_benton ... _2_pro.htm

It's only £8 over my budget, and has isolated inputs so less noise?

Would this power the following pedals, including the ones not on the board for now:

Morley Bad Horsie
Boss TU-3
Joyo Ultimate Drive
Behringer HM300
Marshall GV-2
Biyang Metal End
TC Electronics Nova Modulator
Boss DD-20

As you can see I would have a total of 8 pedals and the Nova is 12V?

I just feel spending a little over budget like this would pay dividends with no noise.

I'm sure you'd notice a difference using a PSU with isolated supplies, but whether it's enough of a difference to be worth spending a lot more money for a PSU is really going to be down to your particular mix of pedals , and the order they are in.

And it's unlikely that you'd get the chance to try your pedalboard out with a different PSU for a basic comparison. If you are happy spending £200+ per pedal then a £150-£200 PSU serving 8 or more of them isn't going to phase you. But if you are all Tone City or Mooer etc. then an expensive PSU does become a relative extravagance.

I hear you there. I've almost always bought pedals cheap or second hand.

So it sounds like seeing as I almost never spent £100 on a pedal (except once), you recommend the cheaper PSU without isolation? Some of the sound samples on YT are... interesting.

Wouldn't touch it with a bargepole. Not because it's got bad specs, but because you'll get a Europlug PSU with it plus a Euro to UK adapter plug. All physically very wobbly and very unstable.

As Wonky says it depends on the pedals used. I have :-

Cry Baby
Seymour Duncan Pickup Driver boost
TC Vintage Dual Distortion
Dr Tone 'Analogue'* Delay
Mooer Pitch Shifter
TC DittoJam Looper
TC Mini HoF reverb

So that's a fair mix of analogue and digital pedals and while, in theory, that lot should exceed the 500mA it all works fine, no noise, buzz or hum.

OTOH, I have a small board for acoustic gigs with :-

Tone Dexter
TC Flashback
TC DittoJam

I normally power it with Li-Ion power packs** and it needs a separate supply to the TD or it generates low level background 'digital hash'. This is not a problem as the TD is pretty power hungry and a single pack only lasts about 2 hours with everything on.

A agree that the wall wart would put me off though Thomann have been supplying proper UK PSUs of late so you may be ok. I'd still rather have a proper mains power box though.

* The Dr Tone 'Analogue' Delay is a £30 pedal from Dawsons and is actually digital. Sounds great though.

** Rockboard or PedalTrain.

The only multi-pedal PSU I can actually recommend is the Voodoo Labs Pedal Power 2 plus, as I've got two of them for my board. IEC mains input, and linked with a short IEC to IEC lead so I only need one mains cable. Even then, they are not perfectly isolated and I did have to power two digital pedals from different units as they were unacceptably noisy when powered from on the same unit.

On principle I don't like PSUs with an external 12v or 18v wall-wart PSU with a thin power cable to the distribution PSU box, as that seems a very weak link. You can package them up if you have the right pedalboard (or build your own specifically) so you can run a mains cable to the pedalboard, but I still don't like bodges like that.

Ok thanks everyone this has all been a lot to take in.

Sam I believe is correct that they should now be supplying UK kettle leads (I looked it up) and given his experience with the PowerPlant, I think that's what I'll go for, not the isolated one.

I just feel given my pedalboard is cheapo (all the "expensive" pedals were second hand except the wah), more money isn't justifiable as was suggested earlier.

Thanks to all for entertaining my anxiety and indecision!

EDIT: Also Thomann do returns if unhappy!

I was going to add that Thomann's return policy is excellent. I have returned couple of things and the process is very easy.

The only issue I can foresee is that of polarity, check all your pedals use the same (usually centre -ve) polarity. The HB uses simple leads to reverse the polarity and that won't work in every case and is more likely to introduce hum even if it does.
