What is that STAIN on the FRONT of nearly every vintage AMPEG amp?

Discussion in 'Live Sound [BG]' started by scottsnellgrove, Feb 19, 2021.

  1. Really, what is that stain on the front of just about every vintage Ampeg amp? I thought it was just me. . . but the more I lookled at ...the more stains that looked alike kept showing up! ! ! What is it? How do you get it off?

    It's that brown stuff...I thought it was from a spill or two or three. . . the more pics of vintage Ampeg amps I looked at. . . the more I started noticing those spots... and the all look similar???????

    Did you mean the amp or the cabs in the pic?

    Beer or soda, that someone left on top of the cab, which rattled off during a performance.

    It's why they went to black grille cloth.

  14. Oxidation brown is what I see. Some metallic tinsel thread in their sparkly grill cloth?

    Battle scars from whatever drink the bass player put on the cabinet.

    That would mean there is iron in the threads used to make the grill— probably not. Easy test- does a magnet stick to it?

  18. Ever see an apple slice turn brown? That's from oxidation. Something doesn't have to be ferrous or magnetic to oxidize.

    Bass players girlfriends have been known to sit on top of cabs while they practice.

    As for the stain, I have no idea what that might be. I just thought I'd share that random factoid.
