My Bass emits a small buzz that gets louder

My new Bass Ibanez SD Gr replaced my Fender Bass. A jolt or stomp on the floor will cause a vibration that cause a buzz that gets louder until muted. I didn’t have that problem with the Fender Bass. I have a Fender LT Rumble amp. Do I adjust the knobs on Bass and amp? I have 5 knobs and 2 switches. I wish they had a knob on both the amp and Bass that says “Basic Bass”


Sounds like feedback to me. I’m guessing this happens when your bass is in it’s stand, that is sitting in front of your amp, which is powered on and cranked up. Am I right?


You are so correct Sir.
