I've got a few decent amps but it seems like on every one there is a little more hum or electrical noise coming through than should be. I play through single coils mostly and understand that it's their inherent nature to hum however this is a bit over the top and makes some pedals almost useless for me. I'm almost certain its crappy power in my house as at other locations all my amps are much more quiet. Has anyone had any experience with using power conditioners? Any thing to look at be concerned about when shopping for them? Any help is appreciated.
