Fender Blues Junior IV (Red Snakeskin/Black)

The Fender Blues Junior IV in Red Snakeskin/Black finish is a 15–watt tube combo amplifier designed to bring classic American tone to the stage and studio. This compact workhorse runs a quartet of power tubes through a single 12–inch Jensen speaker, delivering overdriven warmth and dynamic headroom that responds to playing touch. The striking cosmetic treatment wraps the cabinet in textured vinyl with contrasting chrome hardware and a black grille cloth, making it stand out in any setting.

Under the hood, this all–tube design employs a trio of 12AX7 preamp valves and a pair of EL84 output tubes, with a single 12AT7 handling reverb recovery duties. The Fat switch reconfigures the midrange voicing to thicken single–coil tones or add heft to humbuckers. Onboard spring reverb adds dimension, while the master volume lets players dial in preamp saturation at manageable output levels. The single 8–ohm input accepts standard instrument cables, and the closed–back cabinet design focuses low–end projection for punchy bass response across the frequency spectrum.
