Inspired by the increasing popularity of American amplifier designs, particularly those from Fender and Vox’s own immediate successes, Jennings commissioned the development of a new line of amps that would bridge the gap between British voicing and American tonal characteristics. The Casino series was the result. The intention wasn’t to directly compete with existing American models, but rather to offer a British-made alternative with a unique identity.

The initial models, introduced in the early 1960s, were relatively simple in design, often featuring a single channel and a limited set of controls. However, as the series progressed, more sophisticated circuits were introduced, incorporating features such as tremolo, vibrato, and multiple inputs. These advancements reflected vox’s commitment to innovation and their desire to provide guitarists with a versatile sonic palette. They weren’t solely focused on purely replicating the characteristics of the Fender Twin Reverb or the Marshall JTM45; they were attempting to create something distinctly vox, but with a nod to popular trends of the time.

The Circuitry and Components

The heart of the vox casino’s sound lies in its circuitry. While sharing some similarities with other vox amplifiers of the era, the Casino series employed unique circuit designs and component choices. Many models utilize ECC83 (12AX7) preamp tubes and EL84 power tubes, a combination known for its bright, articulate tone. The power transformers and output transformers were custom-made for vox, contributing to the amplifier's distinctive sonic signature. A key feature of many Casino amps is their use of a negative feedback loop, which helps to reduce distortion and improve clarity, creating a sound often described as "chimey".

The quality of the components used in the vox casino amplifiers was generally quite high for the time. Many models featured high-quality potentiometers, capacitors, and resistors, ensuring reliability and longevity. However, like all vintage electronics, these components can degrade over time, so restoration and maintenance are often necessary to keep these amplifiers in optimal working condition. A skilled technician, mindful of preserving the original character of the amplifier, is essential for this type of work.
