Carlsbro

Founded in 1959 by Stuart and Sheila Mercer, in the English town of Nottingham, Carlsbro is among the very oldest British guitar amplifier companies, along with the likes of Vox, Selmer and WEM. The company even sold its famous 50 TOP valve heads to Jim Marshall’s guitar shop before Marshall made amps of his own. The company also makes electronic drum kits and PA systems.
