I seem to get a lot of noise from the power in my house, mainly from the BT Broadband In line adapters that mig my earthing system. Also at my mates house where he has 300 plugs and reams of cable everywhere.Would one of these help?http://www.amazon.co.uk/dp/B000PS5700/ref=asc_df_B000PS57002318313?smid=AAFA5BUP4HVE1&tag=googlecouk06-21&linkCode=asn&creative=22218&creativeASIN=B000PS5700I was going to get an isolated power supply for my effects but just tried my new BoR clone with a battery and as soon as you up the gian you get the same thing, nasyt broadband noise screetching through the amp.I'd just turn it off but usually somebody is using it.....But as a general thing do power conditioners help?
