412 MARS 1960AX Green SHIBASAKI Signature

The Marshall™ 4×12 1960AX slant cabinet loaded with four Celestion™ G12M25 Greenback speakers. The one Shibasaki reaches for on parts that call for warmth, controlled breakup, and a more open midrange — territory where the Bogner V30 turns out too aggressive. The enclosure is a classic Marshall plywood build, distinguished from the standard 1960A by its speaker configuration. In contrast to Bogner-style stiff construction, this cabinet has its own hand in shaping the tone, bringing low-mid body and a slight softness to the top-end transients.

Speakers and why Shibasaki chose this cabinet

Four Celestion™ G12M25 Greenbacks, 25W each. The historical reference that defined classic British rock — a vocal midrange, creamy compression as the speaker enters breakup, and a top end that rolls off naturally without harshness. Less aggressive than the V30, more colored than a neutral monitor speaker — sitting between the two. An option for territory where the Bogner V30 turns out too aggressive: classic-rock voicings, mid-gain rhythm with body, and lead tones that call for warmth rather than slice. The 1960AX with Greenbacks settles in naturally from clean through modern mid-gain without pushing the mix on presence.

Microphone capture — 9 single + 76 mixed-mic IRs

Six microphones across 9 single-mic positions, combined into 76 mixed-mic IRs. The mic configuration was chosen to draw out the midrange weight of this cabinet and the compression character of the Greenback, including off-axis positions that match the tone-shaping flexibility this cabinet responds to. Placement and tonal balance entirely under Shibasaki's supervision. The plywood cabinet voicing of the Marshall™ 1960AX, the vocal midrange and creamy compression of the G12M25 Greenback, and Shibasaki's mic discipline are captured here as a tool that covers classic rock through modern mid-gain.
