Description
Graph Tech Ghost Series Hexpander MIDI Interface Preamp Board (PD-0440-00)
Turn your electric guitar or bass into a high-performance MIDI controller with the Graph Tech Ghost Hexpander Preamp Board. Engineered by Graph Tech Guitar Labs, this micro-circuit board acts as the central brain for hexaphonic pickup translation. It offers guitarists and bassists access to lightning-fast, analog-to-digital tracking curves to control synthesizers, virtual instruments, and software modelers directly from their strings.
Whether you are performing a replacement repair on a seasoned hybrid instrument or installing a fresh, modular MIDI retrofit, the PD-0440-00 delivers unparalleled, low-latency responsiveness. It tracks your exact performance dynamics with pristine accuracy, ensuring no dead spots and no lagging behind your fastest shredding or picking runs.
Key Features
Proprietary Harmonic Dampening System: Say goodbye to ghost notes and accidental tracking glitches. This interface board features a built-in harmonic filter that smooths out tracking errors and string overtones. It provides incredibly accurate, reliable triggering that outperforms standard hex pickups.
Onboard Traktion Optimization Switch: Total compatibility across conversion platforms. The board features an onboard mini "Traktion" micro-switch that optimizes the internal tracking curve. You can toggle the profile instantly between Roland-style and Axon-style configurations to perfectly match your hardware converter setup.
Zero Battery Power Draw: Keep your layout clutter-free. When utilized as a standalone unit connected to a virtual processor, the Hexpander board does not require a separate 9V internal battery. Instead, it intelligently draws its active operational power directly from your external synth or modeling unit via the 13-pin connection cable.
Versatile Modular Architecture: Designed to seamlessly integrate with your existing setup. This versatile interface board is fully capable of operating as a standalone MIDI unit, or it can "piggyback" directly onto a Graph Tech Acousti-Phonic Preamp board—allowing you to blend traditional magnetic pickups, acoustic piezos, and MIDI synthesis concurrently.

System Compatibility Note
This circuit board serves as the exact factory replacement module included native to the following Graph Tech modular installations:
Hexpander MIDI Kits: Basic Kit (PE-0440-00) and Advanced Kit (PK-0440-00)
Dual-System Combination Kits: Acousti-Phonic & Hexpander Combo Kits (PK-0680-00 and PK-0780-00)
Required Accessories: This board is a replacement component only. To build a complete functional system from scratch, it must be paired with Graph Tech Ghost-loaded saddle pickups (or bridge assemblies), a 13-pin output jack harness, and an external MIDI converter engine (such as the Roland GR-55, VG-99, Axon AX-100, or comparable units). Professional installation by a luthier or guitar technician is highly recommended due to the delicate nature of internal circuit wiring.
