Green 4240 (double roll cloth surround), features a new ceramic magnet structure and a cone surround treatment.
The speaker motor action allows the cones to generate micro-cone-fine-granular distortion, which has an alnico-like magnet sound to it. It lacks the traditional crunch at the end of the cone incursion and replaces it with a strong paper chime.
The Green 4240 has a less of a woody texture and more of a tradition paper controlled detailed mid-range with no mud. Preserves and amplifies that string edge, string bite and chime.
Very fast attack with little or no drag and response to picking, and return to neutral, reveals subtle and different types of amplifier and pedal distortion.
