Vintage-inspired Celestion G12M-65 Creamback speakers

Originally released amid rock’s mid-1960s revolution, the Celestion G12M Creamback found in many a vintage Marshall amplifier helped define the sound of the burgeoning blues-rock scene. It’s arguably Celestion’s most prized ceramic magnet speaker, gracing the records of countless all-time greats, including Jimi Hendrix, Eric Clapton, Jimmy Page, and Jeff Beck. The Marshall Studio JTM cabinet’s dual G12M-65 speakers retain the same vocal-like midrange, creamy highs, and aggressive overdriven tone of the original, only with a significantly higher power rating and a slightly improved low-end response to better suit the modern guitarist. For players who clamor for the raw and organic dirty tones that set the stage for Marshall’s dominance of the classic rock era, Sweetwater guitarists agree: the Celestion G12M-65 speaker is tough to top.
