SOLD - Vintage Fender Vibrolux 5F11 Narrow Panel Tweed Combo - USA 1959

Here is a 1959 Fender Vibrolux 5F11 narrow panel tweed combo, a genuine late-’50s Fullerton-built example from the peak of Fender’s tweed era. Sitting between the smaller Princeton and the more powerful Deluxe, the Vibrolux occupies a highly musical middle ground, delivering touch-sensitive response, rich harmonic content, and a very usable output level that works beautifully for both recording and smaller live settings.

This 5F11 circuit is especially notable for its bias-modulated vibrato, one of Fender’s most organic tremolo designs. Unlike later opto-based systems, it interacts directly with the power section, producing a deep, pulsing modulation that feels fluid, dimensional, and highly responsive to playing dynamics. Tonally, the amp carries all the hallmarks of classic tweed Fender design, warm low end, woody midrange, and a sweet, singing top end that opens up naturally as the volume is increased, transitioning from rich cleans into complex, harmonically dense overdrive.

This example presents well as a preserved vintage unit, retaining the character and feel expected of an original late-’50s Fender rather than an over-restored piece. It has been sympathetically updated with a Weber Alnico 10” speaker, a well-regarded replacement choice for this circuit that enhances clarity, compression, and reliability while maintaining the amp’s original voice and breakup character. Cosmetically, it shows honest age-appropriate wear to the tweed and grille cloth, but remains structurally sound and visually authentic. A highly regarded and increasingly sought-after Fender tweed model, this Vibrolux delivers classic tone, musical versatility, and true vintage character in equal measure.
