Hi folks, My signal chain is hot enough that even at low volumes at band practice I get fairly significant hum or buzz coming through my amp. This can be stopped by turning my bass all the way down or even by resting my hands on the strings. This is my first active bass so I haven't had to weed this out before. The hum is especially obnoxious at practice, and I can't imagine what it's going to be like live with in-ears. My chain is Dingwall NG-2 -> Peterson StroboStomp -> Darkglass B7K -> BBE Opti-comp -> Hartke 2500 -> Hartke 4x10 (I have a 482i Sonic Maximizer that I run through the effects loop of the amp at smaller shows, if this makes a difference). Do I need a noise suppressor or something like it, or is my issue rooted in something else? If option one: which should I get? If option two: what am I doing wrong? Thanks!
