I last logged in here 2.5 years ago, and last posted over 4 years ago, but today I was so incensed by a product that I have broken that incredible dry spell to let you all know what I think! I recently needed to get my pedal board back in action for an upcoming gig. I had one pedal more than my old power daisy chain could handle, so I headed to my local music shop and came home with a Visual Sound 1 Spot. I wasn't happy forking out AUD$55 for a lowly power supply and daisy chain cable, but I was in a hurry to get my rig in order and my first impressions were good. It's compact, has a high current rating, the daisy chain cable is decent quality with right angle plugs etc etc. All that changed the minute I plugged the power supply in. The noise in my system went up considerably. I did all the usual checks, looking for dodgy patch cables, dirty jack sockets etc. Then I started to suspect a faulty pedal, or perhaps the supply was being loaded down, so I started pulling them out one by one. I stripped down the signal path until it was a single pedal, two cables and the 1spot - the noise had not changed at all. Finally I started to suspect my amp, so I swapped the 1spot for an old "DaiChi" brand (linear) power supply and... ZERO NOISE! Testing showed that this was not an issue of voltage ripple caused by overloading the supply. So, why is it so noisy? All I can suspect is that there is some issue with the 1spot ground - either it's coupled to the mains supply somehow, or the common mode rejection of the switch-mode regulator is poor, or something about the design is particularly adept at circulating ground currents... I don't really know. In the end, all that matters is that it's no good for it's intended purpose. There is one other possibility - I got a dud - there are a lot of good reviews about these things after all. However, part of me can't help but suspect that people who have a 1spot they think is noise-free either aren't listening as critically as others do or the noise is being masked by other, louder sources of noise in their system. So I returned the 1spot today. I had a heck of a time explaining the situation to the staff spit, but that's a subject for a whole different rant which my wife will be lucky enough to hear later tonight! nifty PS: Visual Sound claim their daisy chain is "The ONLY daisy-chain available with right-angle plugs!" which is absolutely not true. The Power-All (Godlyke) daisy chain cable has high quality right angle DC plugs. All connections are the "spring-loaded contact" type, not just the input socket, and it has ELEVEN output plugs and heavier duty cable. I can't speak for the Powerall power supply, but if I get the opportunity in the future to test one out I will jump at the chance!
