Marshall Lead 12 amp….
“a favorite recording amp for such legendary players as the Rev. himself… Billy F. Gibbons from ZZ Top. Here’s a quote from the book “The History of Marshall” by Michael Doyle:

Billy F Gibbons. He recorded such guitar greats as “My Head’s In Mississippi” with this amp, and I am eternally in his debt for bringing it to my attention!…"
