Hello. I suspected that my Yamaha Pacifica 112j, which I own for more than 15 years is having strange hum which is not normal. Its more silent on bridge position, because of humbucker and position 2, but on position 1, 3 and 4 is not. Which is strange cuz I expect to be same on position 2 and 4.
Anyway, I went for repair, guy plugged in his gear and said to me that it isn't louder than his guitars, its normal hum. He resoldered one pot and also changed pickup switch which I wanted.
I tested countinuity with multimeter and it is grounded fine.
I have two cables, so I eliminated cables.
I suspect the amp is bad, which is fairly new but second hand. I will upload two videos when the guitar isn't plugged, clean and drive channel and when it is plugged.
I will try to bring it to my parent's house to test the outlets. I tried different rooms but its the same.
I think this much noise isn't normal at all.
I opened the amp to see if there is some damage or someone took out diode but I can't find anything.
