The Park 1210 and 1240 Rock are guitar amplifier heads produced by Park, the Marshall subsidiary brand founded in 1965. Built on Marshall JTM45/plexi-era circuits, Park amplifiers offered the same transformers, components, and tonal character as their Marshall counterparts but were marketed under the Park name to reach additional retail channels. These models deliver the classic British crunch — warm on the clean side, raw and harmonically rich when pushed — that defined British rock of the late 1960s.
