geoham Posted October 22, 2012 Share Posted October 22, 2012 Hi, I wonder if someone could help me. I have a six outlet PSU powering all pedals. There is a terrible hissing noise, which I've narrowed down to my Ashdown Drive Plus pedal.[list] [*]Ashdown connected to PSU, all other pedals powered by battery - no noise [*]All other pedals connected to PSU, Ashdown powered by battery - no noise [*]Ashdown and any other pedal connected to PSU - very hissy. [/list] This isn't just the usual hum you get when using pedals with a PSU - it's very loud. I've also tried the pedals in different orders, connecting to different outlets on the PSU, but the hissing remains - except in the scenarios described above. I've tried two basses (Fender Jazz and Ibanez ATK) and several cables - it makes no difference. I can just run the Ashdown on batteries, but if anyone has any suggestions how I can resolve this, I'd appreciate it!. Thanks, George Quote Link to comment Share on other sites More sharing options...
Thatguy59 Posted October 22, 2012 Share Posted October 22, 2012 I can't be too certain, but send ashdown an e-mail about it or pop a question on their facebook, they're usually very helpful people Quote Link to comment Share on other sites More sharing options...
geoham Posted October 22, 2012 Author Share Posted October 22, 2012 I'll give that a go - though my cynical streak is expecting the 'use the supported PSU only' line.... I'll let you know how I get on. Thanks, Quote Link to comment Share on other sites More sharing options...
Cyrene Posted October 22, 2012 Share Posted October 22, 2012 Hi. I'm having the exact same problem with my Ashdown Chorus Plus. It's set up as last in the series of 4 pedals. I'll let you know how i get on. Quote Link to comment Share on other sites More sharing options...
geoham Posted October 23, 2012 Author Share Posted October 23, 2012 Suppose it's good to know I'm not the only one! I've contacted Ashdown via their website - I'll post their response here. Quote Link to comment Share on other sites More sharing options...
geoham Posted October 24, 2012 Author Share Posted October 24, 2012 Got a response from Ashdown - basically, they suggest a separate PSU for the Drive Plus pedal. Quote Link to comment Share on other sites More sharing options...
Cyrene Posted October 24, 2012 Share Posted October 24, 2012 Pretty standard then. Quote Link to comment Share on other sites More sharing options...
