gibson guitar amp

My Gibson Sg special that crackles some on the input 1 of my amp but not the input 2. Is it the guitar or amp?
My Epiphone Les paul doesn’t crackle on either input.It only crackles on a low volume, not a high volume. I have noticed that my gibson has a much stronger and louder sound. I am wondering if it is the guitar or amp.
amp may not be able to handle the stronger signal it recieves from the better pick ups in your gibson….get your amp serviced!!
