Park Amplifiers is a British-style guitar amplifier brand with roots dating to 1965, when Jim Marshall began building amps under the Park name for distributor Johnny Jones and Crossland (Park was the maiden name of Jones's wife) as a workaround to Marshall's exclusive distribution deal with Rose-Morris. Original Park amplifiers were produced from 1965 until 1982, essentially using Marshall circuits and tooling, and included 45- and 50-watt builds along with 100-watt heads and the KT88-powered Park 75. Vintage models such as the 1229 and the Park 75 remain collectible among players seeking an alternative voice to period Marshalls.

The modern incarnation of the brand is led by Mitch Colby, a longtime figure in the US amp industry who spent roughly three decades with the American distributors of Marshall and Vox before founding Colby Amplification in 2012. Park was folded into Colby's operation in 2013, with the lineup aiming to faithfully recreate the sound, feel, and cosmetics of 1960s and 1970s British amplifiers. The catalog builds on traditional "45" and "50" circuits and extends to higher-powered 100-watt designs and reissues of the Park 75.

Alongside the classic-voiced heads, Park offers lower-wattage amps such as the Little Head and Little Rock, plus the P1800 combo and P1800HiLo head, which draw on the Watkins Dominator and Marshall 18-watt combo traditions. The amps are hand-wired and produced in small numbers, aimed at players and studios looking for vintage British tone in stage- and recording-friendly formats.

Park Amplifiers has 17 products cataloged on Equipboard, including Guitar Amplifier Heads, Combo Guitar Amplifiers, and Bass Combo Amplifiers. Their gear is featured by 10 artists, with the strongest followings in Rock, Blues, and Pop. Notable users include Billie Joe Armstrong, Rick Beato, and Robert Poss.
