To review, I tested the amp every which way I could think of, AND played
bass through a different amp. Couldn't duplicate the problem. This
playing again through the different amp - WHAM! The noise.
Get out the surgical tools.....this is nuts.
Is this all in the same room/building?
If so I'd get someone to look into your mains power...
Not all in the same building, but it doesn't matter. I found the problem
today. Background: Thursday, I made sure to play the bass for several hours
through my practice amp, hoping to hear the offending noise. It didn't
happen. This morning, though, it finally happened. Two weeks ago, I replaced
the output jack on the bass, so my first thought was that even though the
solder joints appeared perfect, maybe they weren't. I popped off the circuit
board cover and used a pencil to jostle the wires, tap the circuit board,
etc etc. Nothing happened.
The phone rang, and while talking, my fingers were sort of mindlessly
tapping on the smaller cover on the battery compartment. Voila. Huge noise.
My first utterance was of a highly technical nature: "WTF??" To make a long
story short, one of the circular female terminals on the battery wires had
been stretched just enough to occasionally lose contact with the battery.
Just tapping on the cover was enough to cause the loss of contact. But, for
99% of the time I was playing the bass, normal motions did not cause the
battery cover to come into contact with folds of clothing or whatever.
Problem fixed. The guy at Ampeg will find a fax, a voice mail and an email
telling him not to ship the replacement amp, if it's not too late to stop
it. If it's on the way, I'll offer to cover the shipping.
