After I moved to this new apartment, it did not have this noise right away but it started to get this weird hum/hiss/buzz sound. It sounds a lot worse with the headphones (because it is right next to you ear). It is worse when I using single coil guitars. Thinking it could be ground loop, I used the power conditioner from Furhman? still had that same noise. I took it to a shop and people there said there is no issue. FS1 is boost, FS2 is overdrive, FS4 was compression pedal.
When I unplug the guitar, there is no noise. Using the position 2 and 4 from start cuts the noise off but when you play that noise can be heard in the back and leaves the trails of the noise.
I tried doing everything, plugging just the pedal in the power, trying it in the different room etc. Nothing seems to work so far. I will be taking it to different house maybe in few weeks but other than that I have no idea what is causing this.
What could be the issue?
