The driver bridge functions like a speaker designed to excite strings rather than move air. Through the principle of sympathetic resonance, any strings tuned in harmony with the incoming signal begin to vibrate and resonate naturally.

The assembly consists of three main components: the magnet, the coil, and the clamp. Each part has been developed through extensive testing and refinement, and is precision machined in-house for maximum performance and reliability.

At the core of the system is a powerful ceramic ring magnet paired with a steel pole piece and magnetic plates that focus and shape the magnetic field. The drive coils are rated to handle 100W RMS at 4 ohms per side, yet can be powered easily by most home stereo amplifiers or compact modern amps. Even a small desktop amplifier provides more than enough power for typical operation.

The clamp serves two critical functions: it transfers vibration from the coil directly into the strings, while also suspending the coil precisely within the magnetic assembly for efficient and controlled movement.

The key selector allows the player to quickly choose which strings are free to resonate and which are muted through a system of rising and falling levers. While only strings tuned in harmony with the input signal will strongly resonate, every string responds to some degree, and too many out-of-key strings can introduce unwanted dissonance.

The system is based on the natural pattern formed by arranging all major key signatures around the circle of fifths. In this sequence, each neighbouring key differs by only a single note, allowing smooth transitions between tonalities. Rotating the selector moves through all 12 major keys, while also providing access to their relative minor scales and related modes.

This configuration covers the vast majority of musical applications, while still allowing complete flexibility. All levers can be easily disengaged, enabling custom scales, alternate tunings, or fully chromatic setups.

The custom-built Sidewinder pickups have been carefully engineered to deliver crisp high-end detail, a warm and balanced midrange, and a full, powerful low end.

The dual coils are mounted sideways in reverse phase for effective hum cancellation, while powerful ceramic magnets are positioned externally with their south poles facing outward. A central steel blade acts as the shared north pole for both coils, concentrating the magnetic field into a precise point directly beneath the strings.

This unique configuration combines many of the rich, noise-free characteristics of a traditional humbucker with the clarity, articulation, and top-end response more commonly associated with single-coil pickups.

The brushed brass and stainless steel enclosure subtly warms the overall tone, while the adjustable base plate allows pickup height to be fine-tuned from underneath the instrument.

The strings are chromatically tuned across a three-octave range, beginning at C2. Fine tuning is handled by a combination of cello and viola tuners, allowing precise adjustment to match other instruments or sound sources and helping extract the fullest tonal potential from the instrument.

At the opposite end, traditional piano tuning pins provide broader pitch adjustment and are ideal for bringing the strings into range quickly. In experienced hands, these pins alone are capable of achieving highly accurate tuning.
