# Steve Morse Model custom wiring: Tele switch, add-bridge mini and on-on-on middle mini

Canonical page: https://guitarwiring.app/wiring-diagrams/dimarzio/steve-morse-model-custom-wiring

Two humbuckers, VS-1 middle, HS-3 top coil · Three-way Tele switch · DPDT on-on mini (add bridge) · DPDT on-on-on mini (middle single) · Volume · Tone

DiMarzio's Steve Morse Model custom wiring: a DP205 neck humbucker, DP108 VS-1 middle single, DP117 HS-3 used as top coil only and a DP200 bridge humbucker. A three-way Tele switch picks rear single, neck or bridge; a front on/on mini adds the bridge; a rear on/on/on mini chooses the three-way, the three-way plus the middle single, or the middle single alone, into 500K custom-taper volume and tone pots with a .022 µF capacitor.

## Specific to this wiring

- Main Switch = 3 Way; Rear DPDT Switch = On/On/On; Front DPDT Switch = On/On.
- Three-way switch for Tele (EP1105): 1 = rear single, 2 = neck, 3 = bridge.
- Front DPDT mini switch, 2 position (EP1106): down = add bridge.
- Rear DPDT mini switch, 3 position (EP1108): up = middle single only; mid = 3 way + middle single; down = 3 way.
- On the rear mini switch each left lug is jumpered to the lug beside it on the right (top, middle and bottom pairs).
- On the neck and bridge humbuckers the black and white leads are joined and insulated.
- The HS-3 is drawn as top coil only with red, bare and black leads: black goes to the Tele switch, red and bare to the volume casing.
- The VS-1's black lead is the signal lead (to the rear mini switch) and its white lead goes to the volume casing.
- The volume's middle lug feeds the jack tip; the tone's middle lug is wired to the volume's input lug and the capacitor sits on the tone's end lug.
- The thin black lines drawn inside the Tele switch body are read as the switch outline, not as jumpers: a jumper there would contradict the sheet's 2 = neck, 3 = bridge legend.
- The switch tags are not labelled in the source, so they are mapped by what each does.

- The catalog Tele switch model's slot roles assume neck / neck + bridge / bridge, while this sheet puts the rear single, neck and bridge on positions 1, 2 and 3; the engine's selection rule (selectionReachesTip) therefore misjudges it (see ruleExceptions), so this reference is topology-only. The engine's per-position pickups match every legend state.
- The expected states are written from the sheet's legends. The mini switches are modelled with switchPosition; which lever direction reaches which throw follows the legends, not a lug label.
- The source's 500K custom taper is not reproduced: both pots use the stand-in's audio taper, so settings between the knob ends are approximate.
- The HS-3 top coil and the VS-1 are modelled as generic single coils; hum cancelling and phase describe the generic models, not measured DiMarzio pickups.
- Pickup resistance is not specified, so no numeric meter readings are given.

## Check before plugging in

- Rear mini up: the meter across the jack reads only the VS-1, whatever the Tele switch does.
- Rear mini down, front mini up: Tele switch 1, 2 and 3 read the HS-3, the neck humbucker and the bridge humbucker in turn.
- Front mini down: the bridge humbucker is added in parallel in Tele switch positions 1 and 2.
- Each taped black–white joint should read open to ground.
