Would you like to know what the Park 75 is all about?

According to The History of Marshall, when Jim Marshall began building amps, the distribution was very limited. A guy by the name of Johnny Jones made a deal with Jim to be an exclusive distributor of Marshalls in North England. When Jim began to expand, Johnny Jones lost his exclusivity. Jim decided to build amps for Johnny under a different name. That name was "Park." Park was the maiden name of Johnny's wife.

The Park 75 was a Marshall 50 with KT88 tubes instead of EL34 tubes. The first Park amps were basically JTM45s.
