Fender FSR Blues Junior IV (Black, Greenback Speaker)
Fender · amplifier
The Fender FSR Blues Junior IV is a Fender Special Run (FSR) variant of the Blues Junior IV, a 15-watt single-EL84 tube combo, fitted here with a Celestion Greenback speaker in place of the standard-issue driver. The Greenback swap gives this FSR edition a distinctly vintage-voiced, slightly compressed midrange character compared to the stock speaker, aimed at players wanting a more classic British-flavored breakup from the Blues Junior's well-regarded tube circuit.
