The golden tones of the Fender Blues Junior Lacquered Tweed combo amp are generated by an all-tube signal path using a pair of EL84 output tubes and 3 - 12AX7 preamp tubes. Add renowned Fender reverb, flexible controls, FAT switch for mid boost, and you're in business. And just look at that chrome panel, that tweed finish with vintage-style brown and gold grille cloth, and those vintage pointer knobs!
