The **AB1.6-R** is a specific guitar model from the **Solar Guitars** "Type AB" series, designed by Ola Englund. While it is a musical instrument, its internal "electronic parts" are what define its high-output, low-noise signal path. --- ### Core Electronic Components | Component | Specification | Function | | :--- | :--- | :--- | | **Pickups** | Duncan Solar (Alnico V) | High-output humbuckers designed for clarity in high-gain settings. | | **Potentiometers** | 500k Ohms (Master Volume) | Standard resistance for humbuckers to preserve high-end frequencies. | | **Switch** | 5-way Blade Switch | Allows for coil splitting and parallel/series wiring options. | | **Jack** | 1/4" Mono Output | The physical connection point for the instrument cable. | | **Shielding** | Conductive Paint / Foil | Applied to the cavity to reduce electromagnetic interference (60-cycle hum). | --- ### Pickup Configuration: Duncan Solar The heart of the AB1.6-R electronics is the **Duncan Solar** pickup set. These are passive pickups voiced specifically for modern metal: * **Bridge Pickup:** Focused on "tight" low-end and aggressive mids to cut through a mix. * **Neck Pickup:** Smoother, with more sustain for lead playing and fluid cleans. --- ### The 5-Way Switching Logic Unlike a standard 3-way toggle, the 5-way blade switch provides a wider tonal palette by utilizing **coil-splitting**: 1. **Position 1:** Bridge Humbucker (Full Power) 2. **Position 2:** Bridge Split (Inner Coil) 3. **Position 3:** Bridge + Neck Humbuckers 4. **Position 4:** Neck Split (Inner Coil) 5. **Position 5:** Neck Humbucker (Full Power) --- ### Technical Schematic Overview If you were to open the back cavity, the wiring logic generally follows this standard high-performance configuration: ```text [Pickup Selector Switch] | +---- [500k Master Volume Pot] ---- [Output Jack] | [Grounding Wire to Bridge/Evertune] ``` *Note: The "R" in AB1.6-R often denotes the "Roasted" Maple neck, but the electronics remain consistent with the high-spec standards of the 1.6 series, which prioritize minimal signal degradation.*
