Brilliant Pedalboard PSU
Jim White Weymouth, 04.04.2020
I bought this to use with the Harley-Benton Spaceship 60 pedalboard (see separate review). I was first attracted by the price, which is roughly half that of the “name” brands (Voodoo Labs, for example, which I was originally looking at as I’ve owned one in the past). The ISO-1 Pro is a beautiful piece of kit (if such a thing can be called beautiful of course **ahem**) and is very well made and sturdy, with a brushed grey metal case. It has eight outlets, all capable of 500 mA (which is quite important for digital pedals, for example, but more for my Boss WL-50 wireless guitar pedal, which draws 300 mA when the transmitter is plugged into the pedal to charge). I’m very impressed with this thing so far; my only gripe is that the mains lead is a two-pin European type, but Thomann send a free UK adapter to solve that problem. I have yet to use the PSU/Pedalboard for a gig, mainly because of the current coronavirus situation, but as soon as I do I will update this review.

A bargain, but I would go with the ISO-2
RomanBirdDog, 08.09.2019
It's good to be buying a power supply for a price that seems right! I had been using a daisy chain and it definitely is something else. I power 7 pedals, analog and digital (including a Line 6 M5 which originally comes with a 500 mA adapter) and it's dead silent. I don't know if it's truly isolated or not in the end but I have no reason to think otherwise (except the low price).

The unit looks very good, though I could do without the (bright) LEDs.
It's pretty compact, too.

The main annoying thing is about the cables: 1) they're all the same length, which means some are way too long, and 2) only one end is angled, so if it stays on-board, that eats a significant amount of space. This is made much worse by the fact that there are plugs on both sides of the unit (which at first seemed cool to me). For this reason, I am considering switching to the ISO-2.

Awesome for the price
Flow420, 10.02.2020
All outputs are FULLY isolated, no ground loop noise. Also pretty sillent in terms of other noise. Very basic outputs, so if you only use 9V pedals this is very interesting.
Adapter for this unit is quite flimsy (also the cable for it). One bonus point is that the big transformer is not in the power supply itself so no problems with that giving any noise (especially if you use wah pedals close to the unit).
I wouldn't recommend going on a big tour or something with it, since the adapter can fail on you in rough conditions. Other than that a big recommendation from me!

so far SO GREAT - gorgeous to look at , light, great design and functional
OGASI, 26.08.2019
OK, i got this to power a mix of pedals, kenton midi box and some cyclone TT models

so far it is faultless and running a moog minifooger drive, boss rv6 x 2, behringer OD 300, TT303, TT606, kenton midi thru 5, one more pedal to go to reach maximum (don't have it yet lol)

i should say this in case a reader is not aware, some of the above are digital, some are analogue - NO ISSUES, isolated outs - smooth

con #1 and only (haha if you can call it that)
i have had to supply my own polarity reverse cable for my kenton, still no issues

no noise, no issues, no nothing except nice blue lights (very bright) that sit under a laptop stand

wish i had done this years ago - for roughly 50quid this is a steal

built great, stylish, powerful - cannot recommend more I just wish THOMANN would always supply UK plugs especially when they know the country of residence, free adaptors are great but a UK psu would be better, hint cough

i should add that i only learned of these multi psu things this last year or so, what a great way to have one psu instead of 8!!!! Also, I only learned this harley benton gear is Thomanns yesterday - surprised and not surprised, thomann are a quality distributor/shop so why not have quality gear.
