The Fender Blues Junior IV is a 15-watt tube combo amplifier beloved by guitarists worldwide for its warm tone, compact footprint, and gig-ready dependability. Ideal for musicians who need a reliable stage amplifier or a clear, responsive studio companion, this powerhouse delivers iconic Fender sound with modern circuit modifications.
Fender Valve Tone
Driven by a pair of EL84 power tubes and three 12AX7 preamp tubes, it offers a highly dynamic playing experience that responds beautifully to your touch. This revision introduces subtle yet impactful upgrades that refine its classic foundation, ensuring your core guitar tone remains clear and defined in any musical situation.
Modified Preamp Circuitry
Fender has updated the preamp architecture in the Blues Junior IV to deliver increased fullness and greater tonal definition. Even when pushing the amplifier into heavy overdrive, the modified circuit ensures your guitar's natural voice remains articulate. This enhanced clarity allows complex chords and fast lead lines to cut through a band mix without becoming muddy or losing their distinct character.
Celestion Speaker and FAT Boost
At the heart of this combo sits a 12-inch Celestion A-Type speaker, chosen for its musicality, smooth highs, and extended low-end response. It provides a modern midrange character that barks beautifully when driven hard, making it well suited to classic rock, blues, and indie styles. For moments when you need extra presence, the built-in "FAT" switch boosts the midrange to add thickness to solos. This can be remotely toggled using the included one-button footswitch, letting you alter your dynamics mid-performance.
Smoother Spring Reverb
The onboard spring reverb has been modified to supply the rich, ambient spatial decay that Fender amplifiers are famous for, but with improved smoothness. This tweaked design allows you to dial in everything from subtle space to deep, cavernous wash at any volume level without the effect sounding harsh or brittle.
Beyond its internal upgrades, the amplifier retains its classic aesthetic charm with black textured vinyl covering, a lightly aged sparkling silver grille cloth, and classic ivory chicken-head pointer knobs. The cabinet itself is constructed from 3/4-inch particle board to ensure structural integrity, paired with a steel-reinforced moulded plastic handle for secure transport between rehearsals and gigs.
