    Wildly unstable when warm
  

*by M***E on Reviewed in the United Kingdom on 26 July 2019*

Not brilliant tbhFor some reason the pre-amp /headphone amp that I bought it for, which specify this voltage and amperage, freaks out and shuts down when this power supply gets warm. It doesn’t do this on any other power supply. Frankly I have chucked it at the bottom of a drawer somewhere as I can’t use it for the purpose I bought itIt’s just wildly unstable. Shame.

Get one of these!!! you wont regret it. Makes no noise and is well made. I spent a lot of time trying to find a decent unit and stumbled across this on amazon. The company that sells these are well informed and great communicators they answered my questions very quickly and were very happy for me contact them if I needed further advice, this coupled to the great people on the amazon community that provided great advice meant this was the psu was the one for me. I have just hooked it up and its as quiet as a mouse great in a studio and is very well made Brilliant!!!

    Excellent power unit for FX pedals
  

*by M***K on Reviewed in the United Kingdom on 20 January 2016*

Excellent power unit, works well with the Ditto x2 looper, No hum at all when connected and in use, tough enough to withstand gig use as its well constructed. The red colour makes it easy to find in the gig case and more important that's its the correct power unit for my looper or other pedals. Don't buy cheap as I have done in the past, you only get what you pay for. I can recommend this.
