4 x 12 British Blackback

The Marshall 1960A is a classic slant 4x12 cabinet constructed from Baltic birch plywood, featuring four 12” Rola Celestion 30W “blackback” speakers. Renowned for its robust build and closed-back, angled design, this cabinet delivers a powerful, punchy sound with pronounced midrange, tight lows, and crisp highs. The 1979 vintage Blackback speakers are highly sought after for their warm, dynamic response and rich harmonic character, making the 1960A a staple for rock and classic tones.
