Henriksen Amplifiers began with Bud Henriksen's desire for a portable amp that could authentically amplify jazz guitar. Starting in the 1980s with Henriksen Data Systems and transitioning through software development, Bud ultimately focused on his passion for music. After retiring, he developed the Jazz Amp in 2006, revolutionizing amplifiers with its quality and tone. Despite Bud's passing, his son Peter continues the mission, expanding beyond jazz to serve various musicians with portable, high-quality amplifiers, embodying the belief that better sound leads to better performance.
