The Fortress is a most excellent all-tube amp hand built in the United States. This amp is designed to meet the recording and live performance requirements of the metal band, “Sylvan Fortress.” Sylvan Fortress guitarist Charles Powell has taken a hands-on approach, guiding the design and destination of the Fortress, ensuring that this amp will be the most sought-after amp for metal guitarists around the world who demand a clear, punchy, articulate metal tone that will define the sound of metal for generations to come.

Along with Charles Powell, guitarist Kevin Johnson also helped shape this metal tone machine as mad scientist David Gilman created this modern legend!
