INTRODUCTION

Your “new” ‘63 VIBROVERB amplifier is living proof of the quality and longevity of Fender amplifier designs.

Fender first introduced the VIBROVERB in the early part of 1963. Unlike many of the other Fender amplifiers that were produced for years, this version of the VIBROVERB had a production life of less than 4 months. It is estimated that fewer than 600 VIBROVERB units were ever produced. This limited production is one of the reasons this amplifier has become highly sought after by vintage amp collectors. The VIBROVERB was the first Fender production model to have both reverb and vibrato as built-in “effects”.

The original VIBROVERB shows Fender in a transitional period with amplifiers changing from tweed covering to brown “Tolex” and eventually to black “Tolex.” In the sum- mer and fall of 1963, Fender changed the speaker configu- ration of the VIBROVERB to a 15 inch speaker and the brown “Tolex” covering changed to black. The single 15 inch model is also fairly rare, but the 2-10 version is leg- endary.

Fender’s ‘63 VIBROVERB re-issue amplifier is based on the original cosmetics, sound and circuit. Every effort was made to be true to the original.

Several changes have been made for safety and reliability reasons. A printed circuit board is used rather that the phenolic “parts panel” of the sixties. A 3-prong line cord is required for safety reasons. Minor modifications to the cir- cuit took place since certain parts are no longer available, but every effort was made to keep the original circuit values and sound the same. We resisted the temptation to “improve” the amp with features found on later models like master volume, effects loop or channel switching. In order to improve reliability, a solid state rectifier was used rather than a 5AR4 tube. Since the ‘63 VIBROVERB uses a solid state rectifier, there is one less tube and tube socket than an original VIBROVERB. All internal circuit voltage values have been precisely matched to the new solid state rectifier to insure exact sonic reproduction and no alterations to the “vintage” sound. On the original model, the Reverb / Vibrato Footswitch connected to the unit via 2 RCA style jacks; this has been changed to a more reliable 1/4” jack. The reverb pan cables now connect more securely to the chassis also.

The VIBROVERB is unique in Fender amplifier history by the implementation of its tone circuit. The VIBROVERB was the first and ONLY Fender amplifier to use this type of tone cir- cuit. The treble control is “tapped,” meaning it responds more like an active tone control allowing boost AND cut of high frequencies. Conventional Fender tone circuits pro- vide a small amount of tone shaping even in the “0” posi- tion, but if the VIBROVERB Treble Control is set to about “5”, the response is flat.

The speakers used in the ‘63 VIBROVERB are reproductions of the original speakers made by the Oxford Speaker Company. When Fender started work on this project, Fender contacted Oxford who still had much of the original tooling and documentation of this 10 inch speaker from the early sixties.

The power and output transformers used in the ‘63 VIBROVERB are built to the original specifications, which are still in the R&D engineering files at Fender’s office. The same “direct-coupled” oscillator circuit is used for generat- ing the vibrato. The reverb sound from the VIBROVERB is “warmer” than later Fender amps due to the unique reverb send and recovery circuit.

The cosmetics of the ‘63 VIBROVERB incorporate the brown “Tolex” and “Ecru” grill cloth used in 1963. We have re- tooled the “flat” Fender logo and have added the original tilt-back legs found on so many Fender amps through the sixties and seventies.

It is suggested that you read this manual thoroughly to understand all the features and functions of your new amplifier. The purchase of a Fender amplifier will provide years of musical enjoyment and the ‘63 VIBROVERB helps keep the Fender legend going strong.

WARNING: TO REDUCE THE RISK OF FIRE OR SHOCK HAZARD, DO NOT EXPOSE AMPLIFIER TO RAIN OR MOISTURE!
