Vintage Fender Vibroverb w/ Factory JBL Speaker - USA 1964

Here is a 1964 Fender Vibroverb, a classic blackface-era amplifier from one of Fender’s most important periods of design evolution. Introduced during the major 1963 lineup refresh, the Vibroverb benefited from the renowned AB763 circuit, delivering tighter low end, increased clean headroom, and a clearer, more articulate response compared to earlier models. Its single 15-inch speaker configuration set it apart from other Fender combos, offering a broader, more open low-end character and a spacious overall feel.

This example retains its original AB763 tube chart and correct mid-1960s valve complement, including a GZ34 rectifier, dual 6L6GC power tubes, and a mix of 12AX7, 12AT7, and 7025 preamp valves. It is also fitted with the optional factory JBL 15-inch speaker, a highly sought-after upgrade known for its efficiency, clarity, and extended headroom, allowing the amp to stay clean at higher volumes while maintaining excellent definition.

With approximately 40 watts of power, the Vibroverb sits in a highly usable range for both stage and studio applications. It delivers classic Fender spring reverb and smooth tremolo, with the large speaker helping to fill a room effortlessly while keeping notes balanced and articulate. The result is a rich, open sound that works beautifully for clean tones and dynamic playing.

Favoured by players such as Stevie Ray Vaughan, Jeff Buckley, John Mayer, Jack White, and Dan Auerbach, the Vibroverb remains one of the most respected vintage Fender amplifiers, valued for both its tone and historical significance.
