Rare and known, this Marshall 4x12 speaker comes from the golden age of Marshall-era - late 1971 / early 1972, with classic checkerboard covering, without plastic corners. The rare and highly coveted pre Rola Celestion G12M T1511 Greenbacks - the 55 Hz version and BASS logo. All of these speakers are actually mislabeled (as they all were back in the day), as they all are at 55 Hz resonance and all of them have the favoured Pulsonic cones. This cab is in very good condition considering its age. Checked and ready for a new owner.CONTACT US FOR SHIPPING OPTIONS BEFORE ORDERING
