When the rocker switch is set to "Headphones," the output level remains constant, but the tip is connected to ring internally on the jack making stereo phoning possible. Use the Master to adjust the listening level. Keep in mind the type and quality of headphones greatly affect the performance of this circuit, with the fully enclosed, studio quality type producing the best results.
CONTROL JACKS:
EXTERNAL SELECT: V-TWIN can be controlled by an external switching source to select between two of the three modes. This can be most any tip to ground type switch logic. This feature makes possible the inclusion of V-TWIN into programmable rigs or multiple pre-amp rigs where the units within are controlled by a programmable switcher.
NOTE: V-TWIN must remain in the power-up switch logic to be controlled via this jack. In other words...every time you get ready to use the unit in an External Select situation, remove the A.C. adaptor and plug it back in without choosing any modes...Leave it alone. This procedure clears the switching logic leaving the circuit in the receive-ready state and awaiting commands from the external switching device.
EXTERNAL BYPASS: The Bypass function may also be triggered by an external switching device. This logic is controlled via a standard tip to ground type switch. This jack performs the same function as the footswitch located on the face of the unit. It is wise to use the same power-up procedure as when using the External Select to clear the switching logic.

V-TWIN specifications

The Mesa/Boogie V-TWIN is a guitar preamp pedal that has gained recognition for its versatility, tonal range, and high-quality construction. Designed with the needs of contemporary musicians in mind, the V-TWIN offers tube-like warmth and dynamic response, making it an essential tool for both live performances and studio recordings.

One of the standout features of the V-TWIN is its two-channel design, which provides players with a wide array of tonal options. The Clean channel delivers pristine, shimmering tones, ideal for sparkling cleans and subtle overdrive. In contrast, the High Gain channel offers a robust, saturated distortion perfect for driving rhythms and soaring leads. Each channel features independent gain and tone controls, allowing musicians to sculpt their sound to perfection.

The V-TWIN employs a unique Dual-Triode vacuum tube circuit that is at the heart of its tonal character. This technology emulates the warmth and responsiveness of traditional tube amplifiers, giving players a rich harmonic content that's difficult to achieve with solid-state designs. Coupled with its high-impedance input, it ensures that the pedal retains the integrity of the guitar's dynamic range.

Another key characteristic of the V-TWIN is the built-in EQ section, which includes a three-band equalizer. This allows players to fine-tune their sound even further, enhancing mids, lows, and highs to fit specific musical genres or personal preferences. Additionally, the pedal incorporates a multi-stage gain architecture, enabling an extensive palette of overdrive levels from subtle to aggressive.

Portability and practicality are also fundamental aspects of the V-TWIN's design. Compact and robust, it fits easily on pedalboards, making it an ideal choice for gigging musicians. The unit features a rugged metal chassis, ensuring durability on the road. Furthermore, the V-TWIN can be powered by a standard 9V power supply, simplifying setup and enhancing ease of use.

Ultimately, the Mesa/Boogie V-TWIN is not just a stellar pedal; it is a versatile preamp solution that brings the unmistakable flavor of tube tones into a portable package. With its innovative technology, user-friendly features, and exceptional sound quality, the V-TWIN is poised to be a go-to choice for guitarists looking to elevate their tone and performance. Whether you play rock, jazz, blues, or a fusion of genres, the V-TWIN stands out as a powerful tool for creative expression.
