I have a lot of hum issues in my recording room (it's an ongoing frustration of many years and I have explored many degrees of power conditioning, insulated cables, shielding guitars, draping mic cables over my shoulders when recording tracks- everything short of building a farady cage around the whole house). I've mostly got it under control except when the local bro country radio station sneaks into my backing vocals). Last night I noticed that moving the short speaker cable between my Ampeg head and speaker cabinet changed the amount of buzz in my bass chain. I've had that speaker cable for years and always use it at home because it's so short, but it's probably time to buy a new one. Does anybody have a recommendation for one in this context?
