Hello - I think my issue is one of poor wiring in my house (newer house to), but curious has anyone experienced an annoying sort of static buzz through your amp, that gets MUCH louder at night only? (I believe what happens is I am on the second floor of my house, and the wiring is not grounded as well as it should be) I use a good triplite Iso power supply, mogami gold cable, and the noise is very low in the daytime (unless I crank the treble on my amp- TC BG250). But at night it gets loud enough where it is annoying if I am playing solo bass. (not a problem when playing along with a cd/etc...) I had my bass checked out as far as whether the pickup is going but it is fine. Any ideas on how to fix this? Would it be worth getting an electrician to check the power circuits/grounding?
