London City is a guitar and amplifier brand originally established in 1969 in Amsterdam, Netherlands, by Dutch Sound Experience (DSE) as a more affordable alternative to British amplifier makers like Marshall. The early catalog focused on tube amplifiers and cabinets, including models such as the DEA50, DEA70 MKV, DEA100 MK IV "Super Amplifier," DEA130 MKV, DEA250, PA Slave, and the Reverb Hundred Combo. Many of these 1970s amps became recognizable for their distinctive turquoise/sea-green tolex finish.

After scaling back through the 1990s, the brand was revived with production shifting to Asia and an expanded lineup that added electric guitars and basses alongside amplifiers. The guitar range includes series such as the Comet, Constellation, Dakota, Osprey, Spitfire, and Hurricane, while the bass lineup features models like the B-2 and B-52. Vintage "Made in Holland" London City amps remain collectible on the used market, and the brand is sometimes cross-referenced with Power City, a related rebrand of the same amplifier designs.

London City has 10 products cataloged on Equipboard, including Solid Body Electric Guitars, Semi-Hollowbody Electric Guitars, and Guitar Amplifier Heads. Their gear is featured by 5 artists, with the strongest followings in Rock, Pop, and Metal. Notable users include Max Rieger, Paul Van Bruystegem, and Jonathan Nido.
