Here is a vintage 1964 Fender Vibroverb -Amp electric guitar amplifier. This particular example, serial number A01260, is in very nice condition. The Fender Vibroverb has long been highly coveted by tone fanatics, and for good reason: it is completely unique, and unlike any other Blackface amp with Reverb. Even the original catalog description suggests it “surpasses other amps in tone and power within and above its price range.” The amp once synonymous with, if not responsible for, Stevie Ray Vaughan’s incredible tone, which was also reissued in 2003 (and discontinued in 2008) is considered the holy grail of Fender Blackface amps.
Serial Number: A01260
Tube Chart Stamp: NB (February 1964)
Speaker Code: 137 342 (CTS)
Transformer Codes: –606326, 606327, -606-3-40, 606340,
The Fender Vibroverb utilizes: (1) 5AR4 rectifier tube (in place of a GZ34), (2) 6L6 power tubes, (3) 7025, (2) 12AT7, and (1) 12AX7 preamp/phase/reverb tubes through a single 15″ CTS speaker.
This very early example features all mid-late 1963 manufactured components (transformers/speaker), which is actually slightly unusual for Blackface Vibroverbs, considering the Brown 6G16 remained in production until Fall of ’63, and the earliest of the AA763 Vibroverbs appeared in late-1963. Though all of the components suggest earlier production, the tube chart date stamp indicates that it left the Fender factory in February of 1964.
Probably one of the best sounding Vibroverbs we’ve owned, the original CTS speaker is extremely sweet and musical, with absolutely no fatigue or voice-coil distortion. Typically outfitted with a Jensen or JBL, it is quite rare and unique to find an example featuring an original 15″ CTS. The amp is super efficient, and produces beautifully rich and powerful tone, which is simply superior to anything other Fender amps from the era can offer. Fantastic full range tone at higher volumes, while remaining crispy clean when turned down, the Vibroverb is ultra dynamic and very versatile. Great with any guitar, it’s an inspiring amp you’ll find complementary with any combination thereof.
While the photos clearly illustrate expected use, the inevitable replacement of several capacitors, and an assortment of mismatched tubes, it is completely original where it matters most. The tolex and grill cloth are original, the speakers is original, all of the transformers are original, and all of the hardware is original. Had the amp not sounded so good when we first tested it, we would have considered replacing the random selection of tubes with a more cohesive set, but whether by accident or design, this amp with these tubes sound i-n-c-r-e-d-i-b-l-e.
