I planned on rearranging my pedal board tonight to try and iron out some of the noise thats been bothering me for a while, thinking it may just be down to a faulty pedal, or the way i'm powering them, or even the order theyre in. However, it seems like it may actually be due to some kind of grounding problem. Seeing as though i have VERY little knowledge about "ground loops" and all of that kind of stuff, i figured i'd ask you guys as you all seem to be fairly switched on. Googling helps to an extent but it's not specific enough to my problem.
- Mexican Stratocaster
- Hotrod DEluxe
- 9 pedals
- 2/3's Planet Waves DIY patch cables
- 1/3 Amphenol patch cables
- Cioks DC10 powering 6 pedals and generic power supplys powering the rest
I moved my pedal board close to the amp (about 1.5m away) so i could sit between them. I guess that proximity wouldn't be doing any favours first up. I had only my Empress Para EQ in the signal path, and only the pedals powered by the cioks, plus one other, were powered. Various inputs/outputs were unplugged.Ie. the pedal board was not set up at all. I noticed that the hum would be affected when i moved my hand around the EQ and would decrease when i picked it up and moved it as far away as could stretch from everything. The hum would be affected when i touched the tips of any PW cables, but not the amphenol... i don't think anyway (this may have been entirely coincidental as the pedals with amphenol cables may have been the ones that weren't powered). The hum would be affected when my hands were on the guitar strings, and further so when i then touched the ins/outs. The humming was worst when my guitars volume know was below 9. In fact it was barely audible when the volume was cranked.
Also, there was no noise whatsoever when the guitar went straight into the amp.
I think that about sums it up.
Anyway, i'm totally at a loss here as i really do not know what's going on, so any help at all would be much appreciated.
