Generate a schematic for the following: Schematic 1: Auto Coil Split for Neck Humbucker with Pot Value Balancing Resistor and Push-Pull for Series/Parallel Switching This schematic is adapted from common HSS designs (mirrored for SSH) like those in Six String Supplies and Fralin Pickups, with a focus on automatic coil splitting in position 4 to balance volumes when combining the neck humbucker with the middle single coil. The humbucker is wired for full output in position 5 but can be switched to parallel mode via a push-pull to reduce its output closer to the single coils' level (parallel mode typically drops output by about 20-30% while brightening tone, helping consistency). A 470k-500k resistor is added to balance pot loading: use 500k pots for both volume and tone (optimal for humbucker), but the resistor makes the single coils "see" ~250k for brighter tone without dulling. The second push-pull is used for phase reversal on the middle pickup, adding tonal variety (out-of-phase sounds in positions 2, 3, and 4) without major volume drops in standard phase.
Components:
Pickups: Neck humbucker (4-conductor: e.g., black = hot/start, white = north finish, red = south finish, green = ground/start south), middle single coil, bridge single coil. Switch: Standard 5-way blade (e.g., CRL or Oak Grigsby). Pots: 500k volume (push-pull for series/parallel), 500k tone (push-pull for phase reverse). Capacitor: 0.022µF for tone (humbucker-friendly; use 0.047µF if preferring darker singles). Resistor: 470k (soldered from the single coils' hot lugs on the 5-way to ground, creating effective 250k load for singles). Output jack, ground bus (back of volume pot). Wiring Description:
Humbucker Wiring Base: Connect white + red (series junction). Black to 5-way lug for neck (positions 4/5 on neck pole). Green to ground. For auto-split: Connect the junction (white/red) to a dedicated lug on the 5-way's unused pole that connects to ground only in position 4 (grounds junction for inner coil split, e.g., south coil active). For series/parallel via volume push-pull: In pushed (series) position, junction stays connected as is. In pulled (parallel), switch disconnects junction and connects white to black (hots together) and red to green (grounds together). Single Coils: Bridge hot to 5-way bridge pole (positions 1/2). Middle hot to 5-way middle lugs (positions 2/3/4, wired across both poles for standard blending). Grounds to bus. Phase Reverse on Tone Push-Pull: Middle pickup hot and ground wires routed through the push-pull DPDT: Pushed = normal polarity (hot to switch, ground to bus). Pulled = swapped (hot to bus, ground to switch) for out-of-phase. Volume and Tone: 5-way output (common poles) to volume input lug. Volume output to jack tip. Tone wired standard (between volume output and ground). Add 470k resistor from single coil inputs on 5-way to ground for balance. Grounds: All pickup grounds, pot backs, jack sleeve to common ground. Switch Positions and Sounds (Volume Consistency Notes):
Position Pickup Selection (Push-Pulls Pushed) With Series/Parallel Pulled With Phase Reverse Pulled Volume Notes 1 Bridge single No change No change Baseline single coil level. 2 Bridge + middle (parallel) No change Out-of-phase thin tone Matched singles; minimal drop in phase mode. 3 Middle single No change Out-of-phase (hummy) Baseline; phase adds hum but similar volume. 4 Middle + neck (auto-split to inner coil) No change (split overrides) Out-of-phase with neck Split reduces neck output ~50% to match middle; consistent with pos 2/3. 5 Neck humbucker (full series) Neck in parallel (brighter, lower output) No change Full series louder (~2x singles); parallel drops to near-single level for consistency. This uses all controls: auto-split balances combined positions, series/parallel toggles solo neck volume, phase adds variety. Pot resistor ensures tonal consistency across pickups.sixstringsupplies.co.ukfralinpickups.com
Schematic 2: Manual Coil Split with Partial Tap Resistor and Push-Pull for Phase Reverse This design prioritizes manual control over splitting the neck humbucker via one push-pull, with a partial tap resistor (e.g., 4.7k-10k) to minimize volume drop when split (~30% reduction instead of 50%, keeping levels consistent with singles). No auto-split, but the 5-way combines full hum with singles (use the tap for balance in pos 4). The second push-pull handles phase reverse on the bridge for unique tones in pos 1/2. Includes the 470k pot balancing resistor as in Schematic 1. Adapted from Northwest Guitars and Fralin partial tap ideas.
Components:
Same as Schematic 1, plus 4.7k resistor for partial tap (wired in series with the humbucker's junction ground path). Pots: 500k volume (push-pull for phase reverse on bridge), 500k tone (push-pull for coil split with partial tap). Wiring Description:
Humbucker Wiring: Series junction (white + red) connected to tone push-pull DPDT: Pushed = full hum (junction floating). Pulled = junction to ground via 4.7k resistor (partial split: unused coil bleeds some signal, boosting output). Black hot to 5-way neck lugs (pos 4/5). Green to ground. Single Coils: Standard as in Schematic 1. Phase Reverse on Volume Push-Pull: Bridge hot/ground swapped via DPDT (similar to Schematic 1 but for bridge). Volume and Tone: Standard wiring from 5-way to pots to jack. Add 470k resistor for single coil balance. Grounds: Common bus. Switch Positions and Sounds (Volume Consistency Notes):
Position Pickup Selection (Push-Pulls Pushed) With Coil Split Pulled With Phase Reverse Pulled Volume Notes 1 Bridge single No change Out-of-phase (hummy) Baseline. 2 Bridge + middle No change Out-of-phase with middle Matched; phase thins but volume stable. 3 Middle single No change No change Baseline. 4 Middle + neck (full hum) Middle + neck partial split No change Full hum louder; partial split reduces to near-middle level for consistency. 5 Neck hum (full) Neck partial split No change Full louder; partial drops to single-like level. The partial tap keeps split volume consistent with full (less drop), using both push-pulls for flexibility.northwestguitars.co.ukfralinpickups.com
Schematic 3: Auto Coil Split with Push-Pull for Bridge Add-On and Series/Parallel, Plus Output Attenuation Resistor Building on Schematic 1, this adds a 10k-15k parallel resistor across the neck humbucker's hot/ground in full mode (via push-pull) to attenuate output by ~20-30% without dulling tone much, matching singles better. One push-pull for series/parallel, the other adds the bridge pickup in pos 5 (neck + bridge combo). Auto-split in pos 4. Inspired by Seymour Duncan versatile schemes and series/parallel mods from Six String Supplies.
Components:
Same as Schematic 1, plus 10k resistor for attenuation (parallel with hum in full mode). Pots: 500k volume (push-pull for bridge add-on), 500k tone (push-pull for series/parallel + attenuation). Wiring Description:
Humbucker Wiring: Auto-split as in Schematic 1. For series/parallel on tone push-pull: Similar to Schematic 1, but pulled (parallel) also switches the 10k resistor across black (hot) and green (ground) to fine-tune attenuation if needed. Bridge Add-On on Volume Push-Pull: Pulled position connects bridge hot to neck lug in pos 5 (via DPDT bypassing 5-way). Single Coils and Pots: Standard, with optional 470k balance resistor. Grounds: Common. Switch Positions and Sounds (Volume Consistency Notes):
Position Pickup Selection (Push-Pulls Pushed) With Series/Parallel Pulled With Bridge Add-On Pulled Volume Notes 1 Bridge single No change No change Baseline. 2 Bridge + middle No change No change Matched. 3 Middle single No change No change Baseline. 4 Middle + neck (auto-split) No change No change Split matches middle. 5 Neck hum (full series) Neck parallel (lower output) Neck + bridge Full/parallel + attenuation options keep close to singles; add-on balances by blending. This maximizes versatility: auto-split for combos, parallel/attenuation for solo balance, add-on for extra tones.seymourduncan.comsixstringsupplies.co.uk
