Axiom Home Page Forums General Discussion Technical Questions the dreaded vibration is back on the ep800

The fact the hum was still there when you left Axiom with it and then it was gone at the old house suggests to me a loose/faulty connection/component in the amp. Now that the sub/amp has been moved and bounced around a little the faulty internal connection/component is now causing the same problem. I think Axiom should/will look after you with another new amp/sub as it has a 5 year warranty.
