HSH with rail middle, super switch, volume and tone

Parts and values

“Example part” means any part with the same value and lugs will do; the source does not name a brand. “Generic” stands in for an unspecified pickup: check your own pickup's lead colours before you solder.

Specific to this wiring

• Middle pickup is drawn as a rail hum-canceling single; generic-humbucker-four-conductor-dimarzio stands in.
• Super switch schemeCode HSH_AUTO_SPLIT.

Connections

In soldering order: grounds first, then the switch, the pickups and the signal path.

What each position does

Not simulated: this circuit is drawn for reference only.

• Rail pickup construction is not modelled beyond the four-conductor stand-in.
• 500K custom-taper pots use the catalog 500k audio stand-in.
• The catalog selector model does not reach the output jack on every throw (selectionReachesTip); position labels follow the source sheet, not a verified simulation table.
• Engine rule groundsReachSleeve fails on the transcribed board; passive position analysis is not verified.
• Capacitor-first tone wiring fails toneReachesSignal without adding undrawn grounds; topology matches the source sheet.

Before you solder

• Identify every lead on your pickups against the source's colours.
• Middle pickup is drawn as a rail hum-canceling single; generic-humbucker-four-conductor-dimarzio stands in.
• Super switch schemeCode HSH_AUTO_SPLIT.
• Use a small amount of solder, heat both surfaces, and hold the joint still as it cools. Lead-free solder may have a matte finish.

Check before plugging in

Measure across the output jack with a multimeter on its resistance range. No exact readings are given where the source does not specify the pickups.
