from the celestion website

My G12Ms have got black covers, how are they different to the Greenback?


Although the standard colour for G12M rear covers was green ('field green' it was called originally), G12M and G12H speakers were also made with black, as well as grey, beige and cream rear covers at various times. This was probably due to a shortage of the correct colour plastic to make them from (e.g. late delivery of the raw material). The different colour covers were only a cosmetic change not affecting the acoustic performance of the speakers in any way. Black, grey, cream, beige or green, they're all 'Greenbacks'.

Thanks for responding. That seems like good news coming from a senior menber like yourself. i read that celestion changed the cones on greenbacks around 1979. you've not heard negative things about the 1979 greenbacks?

any idea of value on them. wondering if that 1979 cabinet for $495 is a good deal or if i should hold out for an earlier cabinet.

The blackbacks are very good speakers and quite sought after. Ive got a quad of G12M blackbacks from 1975. They sound awesome. If you play classic rock you cant go wrong with them in my opinion.

I wouldnt hesitate to buy them. $495 is a good deal. on ebay Ive seen date matched quads of blackbacks go for 400 ($650) on their own without a cab.

If you are worried about the cone change in 1979 then just wait for a slightly earlier cab to come along.

I would always recommend buying vintage cabs rather than new or reissue cabs. They hold their value better and are just a hell of a lot cooler. You cant beat that mojo they have when they've been beat about a bit and done plenty of gigs.

Cone info can be very confusing.
This is a very good thread on the subject.
Vintage Amps Bulletin Board • View topic - Pre Rola, Rola, Rola Celestion defined

Regardless, that sound like a good deal.

I just gotta say, "this forum is awesome!" Thanks every one who responded. I think i'm gonna snag the cabinet. i'll post pictures and a review.

i found this link on another site/forum as well. they agree that the blackbacks are good.

So there was a cone change in 1979? is it considered a downgrade? how can i identify if i'm getting the "bad" cones?

Re: Are 1979 Celestion g12m "blackbacks" good?

i found this article about greenbacks: Welcome to LegendaryTones!

which states:
throughout the1970s, the color of the magnet cover was changed (beige, black, etc.), but the basic ingredients, other than a few variances in the cone, largely remained the same, until the late 70s, circa 78-79, when new materials in the cone diaphragm were explored.

can somebody give me the low down on the 1979 blackbacks? I always seem to buy stuff and find out the next day "oh you shoulda got these other ones instead."

I wouldnt worry about it too much. Small changes in the speaker construction arent going to make them significantly different enough to make them crap speakers.

Thats just guitarists for you. They like to spot every tiny little manufacturing change so they can say their older gear is far superior. In my experience any change in the sound is going to be minimal.

when the drummer kicks in no-one will be able to tell the difference anyway.

has anyone played the 1979 green backs and older greenbacks that could share their experience? the problem for me is i can't play the cabinet next to an older one to see the difference.
