I bought this on Reverb new and never removed it from the box. A friend recommended it for a 1x12" cab I got for the studio, but I never ended up setting it up. I'm not using my speaker cabs that much these days, so this has to go!

From Celestion:

The G12M Greenback is perhaps the definitive vintage Celestion ceramic magnet guitar speaker. Developed in the mid-sixties it was quickly adopted by players like Hendrix, Clapton, Beck and Page who typified the louder and more aggressive blues rock playing styles that came to characterize that era.

The G12M-65 Creamback produces the familiar woody G12M tone but handles greater power, making it ideally suited for today’s amps when a vintage tone is desired. The increased power handling brings with it additional low end grunt complementing the warm and vocal mid range crunchy upper- mids and sweet refined highs.
