The result—our ’64 Vibroverb Custom—is a hand-wired all-tube combo amp. Its solid finger-jointed pine cabinet provides thick, resonant tone perfect for the unique, throaty sound of a single 15” speaker. From the front, it appears to simply be a faithful reissue of the rare and collectible 1964 Blackface™ Fender Vibroverb amp, but a few surprise features can be found on the back that’ll kick the tone into overdrive! Diaz’s legendary Vibroverb modifications are on the rear panel—the mod and rectifier switches allow players to enjoy vintage Blackface tones and hot-rodded, cranked-up Texas blues tones bristling with sustain and harmonics. Other premium features include a 15” Special Design Eminence speaker with full, rich bass tone and top-end shimmer, and two powerful 6L6 Groove Tubes.
