THE OFTEN-OVERLOOKED 470K RESISTOR
A small but important detail when combining humbuckers with a single-coil pickup.
The 470K resistor helps the single-coil pickup see an effective load closer to 250K, while the humbuckers retain the benefits of the 500K potentiometer.
This helps balance the brightness of the single-coil pickup without compromising the clarity and openness of the humbuckers.

THE OFTEN-OVERLOOKED 470K RESISTOR
The 470K resistor helps balance the different loading requirements of humbuckers and single-coil pickups.
It allows the single-coil pickup to see a load closer to 250K, helping control excessive brightness while allowing the humbuckers to retain the clarity and openness associated with a higher-value potentiometer.

SUPER STRAT-STYLE GUITAR WITH 2 HUMBUCKERS & 1 SINGLE-COIL PICKUP — SERIES / PARALLEL
DPDT SERIES / PARALLEL • 1 VOLUME • 1 TONE • 5-WAY SWITCH
A complete electronics upgrade with additional humbucker series/parallel switching, providing greater tonal versatility while retaining the core character of the pickups.
COMPONENTS & UPGRADES
CTS B500K Potentiometer × 1 - Volume OR Bare Knuckle 550K 10% Taper Push-Pull Potentiometer × 1
CTS A500K Potentiometer × 1 - Tone OR Bare Knuckle 550K 30% Taper Push-Pull Potentiometer × 1
DPDT ON/ON Switch × 2 - Optional (Allows the humbuckers to be individually switched between Series and Parallel operation)
Treble Bleed Circuit with Resistor × 1 - Helps maintain high-frequency clarity when rolling down the volume
470K Resistor × 1 - Configured to help the single-coil pickup see an effective load closer to 250K while the humbuckers retain the benefits of the 500K potentiometer
Bare Knuckle 0.022µF Mineral Oil Tone Capacitor × 1
CRL or OAK 5-Way Lever Switch × 1
Switchcraft Mono Output Jack × 1
22 AWG 19-Strand Silver-Plated Copper Core Teflon Wire × 1
Premium-Grade Solder & Flux - Used throughout the installation
SERIES / PARALLEL SWITCHING
Series mode provides the full output, warmth, and thickness associated with a conventional humbucker.
Parallel mode produces a cleaner, brighter, and more open response while retaining hum-cancelling operation.
With two independent DPDT switches, each humbucker can be configured individually, providing additional tonal combinations beyond the standard 5-way switching.
BUILT FOR PRECISION
Every connection is professionally soldered, neatly routed, and carefully inspected to ensure reliable signal transmission, consistent switching, and optimal performance from your pickups and controls.
