Port City Amplification is a boutique guitar amp, speaker cabinet, and effects pedal builder based in Asheville, North Carolina. The company hand-assembles point-to-point wired tube amps and is best known for its patented Wave cabinet design, which uses internal 45-degree deflectors to redirect rear-projected sound waves out a port along the front of the cabinet and back toward the player.

The lineup includes amplifiers like the Grandville (offered as a head and combo), the Pearl combo, and tweed-style builds such as 5F1- and 5E3-inspired circuits, alongside 2x12 Wave cabinets in vertical and horizontal orientations and pedals like the Salem Boost and Sahana overdrive. The company also runs amp-building classes, walking students through tube-amp circuits rather than kit assembly.

Port City has been used by artists including Keith Urban, Zac Brown, Jimmy Herring, Dweezil Zappa, Tom Guarna, and Kurt Rosenwinkel, and the brand collaborated with guitar YouTuber Rhett Shull on a signature 30-watt amp focused on clean headroom and tremolo.

Port City has 10 products cataloged on Equipboard, including Guitar Amplifier Cabinets, Guitar Amplifier Heads, and Boost Effects Pedals. Their gear is featured by 10 artists, with the strongest followings in Rock, Metal, and Jazz. Notable users include Tosin Abasi, Paul Waggoner, and Javier Reyes.
