TopHat Amps is a boutique guitar amplifier maker founded in 1994 by Brian Gerhard, originally based in Anaheim, California before relocating to North Carolina in 2005. Every amp is hand-built to order using all-tube, point-to-point wired construction, with circuits rooted in classic British and American designs but re-voiced with Gerhard's own tweaks to tolerances and tone shaping.

The lineup spans the Club Series — the brand's best-known line, available in various wattages and combo or head formats — along with the Club Royale, King Royale, Super Deluxe, Emplexador (a Marshall-inspired Plexi-style amp), and Vanderbilt models, plus matching speaker cabinets and Custom Shop builds. TopHat also offers extensive custom options, letting buyers specify cosmetics and spec-level details on most orders.

The amps have earned a reputation in boutique circles for EL84- and EL34-driven chime and crunch, and are frequently discussed on forums like The Gear Page and the Telecaster Discussion Page Reissue. TopHat competes in a similar space to Matchless, Bad Cat, and Dr. Z — small-shop, hand-wired amps aimed at players seeking vintage-flavored tones with modern build quality.

TopHat has 5 products cataloged on Equipboard, including Combo Guitar Amplifiers and Guitar Amplifier Heads. Their gear is featured by 9 artists, with the strongest followings in Rock and Pop. Notable users include Shane Moran, Taylor York, and Kerry McCoy.
