Fender Blues Junior Tube Set
The Fender Blues Junior Tube Set consists of 3 x 12AX7 preamp tubes and 2 x EL84 power tubes.
The Blues Junior™ III is a 15-watt warm-toned, longtime favorite – the perfect grab-and-go tube amp for stage and studio.
It is known for the fat mid tones characteristic of EL-84 output tubes, warm 12AX7 preamp tube overdrive, real spring reverb, simple control layout, footswitchable FAT boost and external speaker capability.
Additional Blues Junior III upgrades include an easier-to-read black control panel with front-reading text, new badge, vintage Fender “dog bone” handle, vintage-size jewel light, “sparkle” circuit mod, rattle-reducing shock absorbers for the EL84 tubes, highly sensitive Fender Special Design 12” “lightning bolt” speaker by Eminence®, and heavy-duty set-screw “chicken head” knobs.
