The Fender Blues Junior IV continues the legacy of the Blues Junior line, combining classic Fender tone with modern refinements and portability. With 15 watts of tube power, it’s designed for guitarists who want expressive, dynamic tone—whether at home, in the studio, or on small stages.
Fender has updated the preamp circuitry in this version to yield greater perceived fullness and clarity, especially when driving into overdrive. The spring reverb has also been modified to provide smoother, more musical tails. A standout feature is the Celestion A-Type speaker, chosen to balance bright highs, punchy mids, and a tight low end—traits especially helpful when paired with pedals.
This version retains the beloved features of the Blues Junior series: a single channel design, Fat pushbutton for mid boost, spring reverb, and robust tube circuits (preamp & power) that respond to dynamics and guitar volume changes with musical sensitivity. The Black finish and classic styling give it versatility and aesthetic appeal across genres.
Whether you're running cleans, driven tones, or layering effects, the Blues Junior IV serves as a highly expressive, road-friendly tube amp with personality.
