Hi, my bass player plays through an old AMPEG head and an old Sunn Amp. When he plays most of the time there is this rattling noise, and sometimes its so bad it sounds like the bass is distorted, or it cuts out. I'm guessing this is just the age of both the cab, but i was wondering if there is anything he can do, or if he just has to replace the speakers. Any help appreciated.
Take it to a speaker/amp technician or a luthier.
ok. i figured as much. thanks.
