The Marshall 425A and 425B are the associated cabinets in the Vintage Modern line as per Marshall's traditional 4 x 12 design. The speakers used in these mono/stereo switchable cabinets are the new G12C 25-watt Celestion Greenbacks which were specifically developed for the Limited Edition Jimi Hendrix Super100JH stack. Voiced to give that rich and balanced harmonic timbre, they complement the vintage tone of the Vintage Modern Series perfectly.
Vintage and Modern
These are 2 words that don't normally sit comfortably together unless you're talking guitar amplification. The Vintage aspect of course, the tone-fat, smooth, classic and dynamic. The Modern aspect is the feature-set included to enable ease of use and flexibility -- master volume, series FX loop, extra overdrive for those hot "modded" sounds, onboard reverb and a new frequency selective pre-amp topology to facilitate tonal tailoring for specific instruments and musical styles.
