    Product Description

    The PWT 08 is a universal pedalboard power supply with huge 2,000 mA output capacity and 8 standard center negative outlets. Two of these are switchable to 9, 12 or 18 volts, and with the included Y cable they can be combined to a single outlet for 21, 24, 30 or 36 volts maximum output. They are isolated from each other and the remaining outlets. Featuring short circuit and overload protection, the PWT 08 is fully regulated to deliver constant voltage. The unit sports a power on LED, bi-color outlet status LEDs and comes with a set of DC cables and dedicated mains adapter. The PWT 08 is the ideal choice if you have just one or two power hungry pedals or 9 volt effects that can be run on higher DC currents for more dynamics and headroom.

    Bought this to power my first "proper" pedal board and pretty pleased with it! Good: Unit feels compact, feels sturdy and generally well made. Eight outputs is plenty - two outputs are isolated from the other six as well as being switchable between 9/12/18v. I've found it quiet in operation, certainly better than I had previously when I had pedals daisy-chained from a single output. Not so good: Cables supplied are right-angle at one end, straight at the other. Would have preferred right-angle at both ends as straight plugs protrude beyond the end of the unit making it harder to fit under the board. It has a European-style plug, with a UK adaptor supplied. Just looks fugly and feels much less sturdy than the unit itself. Disappointing. First unit I received developed a fault on first day. Anderton's customer service was great and had a replacement in-hand within 48hrs (given it failed on a Sunday, that's pretty good). Second one has lasted few weeks so assuming that first failure was just bad luck. All in all, this is a decent power supply for the money. Certainly I couldn't find one another that had this many ports, with voltage switching, at this price. Only real concern is the wall wart - mine is going to be used at home mostly, if you are gigging might want to think about if that flimsy power adaptor is going to last though.

    8 outlets and a total of 2000 mA (although is 500 mA on 2 outlets only). No issues with it so far but not had it long enough to comment on durability.

    PWT product as described - works great - only I should have checked if it would power my HT-DUAL Blackstar - which it doesn't - but this is my mistake as I know these pedals can be very specific

    For the price, this power supply packs a lot in. The unit itself also feels pretty robust, with it having a tough metal shell. The switchable voltage ports are really handy. However, it has its issues. The wall plug for it is dreadful and of a much lower standard than everything else included. The plug is a European 2 pin type, with a UK 3 pin adapter supplied, but the adapter doesn't lock into place. I've had to masking tape mine on so that the plug doesn't just drop out of the adapter. I'm also having some gremlins with a temperamental supply from a particular socket to a specific pedal and I cannot fathom why. Unsure if that's the power supply or the pedal being a nuisance. For £80 though, it's otherwise very good.
