The Fender Vibroverb is a 40-watt combo guitar amp originally manufactured in 1963 and 1964. It was the first Fender amplifier to incorporate on-board reverb which became a standard feature on many high-end Fender tube amps during the 1960s and 1970s.
Stevie Ray Vaughan’s musical influence has really hyped the blackface Fender Vibroverb. He used 2 in tandem to create his unique sound, and because of him the Vibroverb has become one of the most expensive and sought after Blackface amps on the market.
So, what is so special with the Vibroverb?
Primarily, the 15″ speaker sets it apart from most guitar amps. While most guitar amps have multiple 10″ and 12″ speakers the Vibroverb came with a big Jensen C15n or a JBLd130, which delivers a huge bottom end and wide dimensional sound.
The Vibroverb belongs to the 6L6 Fender family. It is powerful and loud, but in a different way than the 10″ and 12″amps. The Vibroverb initially did not sell very well in 63 and 64. Guitarists possibly thought the amp was more suited for bass players, but the Vibroverb did score big among steel guitar players at the time.
The 15″ speaker is firm in the bass and has lots of sparkle but most importantly, it has an enormous spread, carrying the lower mids to anyone on stage and further afield. Mid frequencies are exactly what you need on stage in an electric band. The mids from a single 15” will blend in nicely with bass, drums, piano and horns, and it will not interfere with the bass like a 4×10″ setup sometimes can.
Of course this is a matter of taste, but a guitar tone with strong mids will contribute to a rich overall footprint in an electric band.

This amp was bought a few years ago from an Australian collector and the only modification we know of is that the original Schumacher transformer was rewound to 240 volts some time ago. We don’t know by whom, or when, but it’s been this way for the past two ownerships. The tremolo pan may also be a later replacement.
Bottom line is this Vibroverb is in fabulous vintage condition. And does it sound good ? – why YES.
This amp has a very warm and nuanced sound, with just enough clean headroom before pushing into saturated overdrive. The circuit offers EQ controls that have a very wide sweep for everything from classic hollow twang to warm, sweet sounds that will delight any rock, blues or jazz player.
This Verb delivers sweet, dynamic clean tones with incredible sparkle and a certain high fidelity clarity that is noticeable as soon as you strum your first chord. Turn the amp up past 4 and she starts to smoothly overdrive with just the right amount of bite and the complex midrange shimmer that makes Fender's Blackface amps so unique.
This is a vintage time capsule that sounds as good as it looks – they don’t make ‘em like this any more.
