| The G12M was the first speaker produced by Celestion to feature a ceramic magnet assembly. Through this, every subtlety of the players dynamic style becomes wonderfully articulated. Today, as ever, the Greenback exudes a warmth and woodiness and yet retains the brightness and punch needed to cut through the rest of the band. Ideally suited to a Blues-Rock style, the Greenback is a must have speaker for anyone seeking classic tone. | |
