I've owned my gorgeous 4003MG for nearly two years now, and bought it brand new. I'm so careful with it I haven't even given it a scratch yet, though I play it daily in different places. I think (thought) I knew every bit of it...until a couple of nights ago while I was on the phone and holding (and admiring) it, when I spotted some green hues under the surface of the finish (as if in the wood itself). Here are two photos to show you...there's no way I could have missed this before. Has anyone seen anything like this happen to theirs?

Thanks!

Yep. My 4003MG has that discoloration on the back of the body. Actually, mine is a little darker and in a couple places, but all near the upper horn. I speculate that it could be the dye from my shirts. I've been playing a lot of shows in hot weather. I assume sweat interacts with the dyes in my shirts and, in turn, discolors the CV. If the sweat/shirt dye thing isn't even possible, then I have no idea what's causing it.

It didn't come off the last time I waxed my bass with carnauba and I haven't made any further attempt to remove it with other compounds. I'm not too worried because no one's going to see it but me and I figure that's the price of gigging frequently. But, if it can be removed, I'm sure someone on the board will have a suggestion.

This is very easy to remove. You just need to buff it off then polish the clear coat. Apparently this is a result of something changing about the SKB cases.

I had it way worse than that on my Mapleglo and it was gotten rid of in under 3 minutes, right before my eyes.

Cassius--what did you use to buff it? Did you use the Scratch X and Zymol treatment?

Cassius - it looks to me like it's under the surface, though. You think it's superficial? From storing it in the original RIC case? I'll try your recommendation asap...thanks.

I didn't, my luthier grabbed it, took it over to a large automated buffing machine (not sure of any better term for it) that most luthiers are likely to own and with a very fine grit he removed all the green and polished the finish back to normal with some Menzerna stuff. All for free as it took him so little time.

I don't think, I know from experience. It's got to be superficial, or "relatively" superficial--enough that a buffer can hit it and not ruin the finish.

Is this going to be an ongoing problem, or will the case eventually quit producing whatever death spores are causing this?

Where did you acquire this info? Do you have any details of when this started?

Try the search function. I remember when this issue came up a few months ago. There were several threads both here and over at the RickResource forum. And as far as I remember, the cause and the cure, in every case, was just as Cassius described.

I didn't take notes but I remember a RIC employee stating either here or on RRF that SKB had to remove an antifungal or something from the case lining in 2008-2009.

My bass developed the issue in humid Missouri; afterwards in the same case in dry Colorado it didn't do it.
