# Randy Rhoads Sandoval Dot V: two humbuckers, two volumes, two tones Canonical page: https://guitarwiring.app/wiring-diagrams/dimarzio/randy-rhoads-sandoval-dot-v-two-volumes-two-tones Two humbuckers · Right-angle three-way toggle · Two volumes · Two tones DiMarzio's Randy Rhoads Sandoval Dot V 1979 layout: neck and bridge humbuckers, each with its own 500K custom-taper volume and tone and a .047 µF capacitor, joined at a right-angle three-way toggle. Each pickup's red lead lands on its volume's middle lug. Drawing: https://guitarwiring.app/wiring-diagrams/dimarzio/randy-rhoads-sandoval-dot-v-two-volumes-two-tones.svg (back of controls) ## Parts and values - Neck pickup: Neck pickup PAF® DP103; generic (Humbucker (four-conductor, DiMarzio colours)) - Bridge pickup: Bridge pickup Super Distortion DP100; generic (Humbucker (four-conductor, DiMarzio colours)) - Toggle (right angle): Switchcraft® toggle switch - right angle (EP1100); compatible example (Switchcraft 3-Way Toggle) - Neck volume 500K custom taper: Volume 500K custom taper pot (EP1201), neck; 500k; compatible example (CTS 500k Audio Pot) - Bridge volume 500K custom taper: Volume 500K custom taper pot (EP1201), bridge; 500k; compatible example (CTS 500k Audio Pot) - Neck tone 500K custom taper: Tone 500K custom taper pot (EP1201), neck; 500k; compatible example (CTS 500k Audio Pot) - Bridge tone 500K custom taper: Tone 500K custom taper pot (EP1201), bridge; 500k; compatible example (CTS 500k Audio Pot) - Output jack: Switchcraft® output jack (2-conductor) EP1301; compatible example (Switchcraft \#11) - .047µF (neck): .047µF capacitor EP1047 (neck tone); 47nF; compatible example (Orange Drop .047µF) - .047µF (bridge): .047µF capacitor EP1047 (bridge tone); 47nF; compatible example (Orange Drop .047µF) - To bridge claw: TO BRIDGE CLAW; generic (Bridge ground wire) ## Specific to this wiring - The source gives no position legend; the toggle is read by function: neck, both, bridge. - On each pickup, the black and white leads are joined and insulated. - Each pickup's red lead goes to its volume's middle lug (wiper) and the toggle is fed from the volume's outer lug, as drawn. - The toggle has two common lugs joined by a short jumper; both run to the jack tip. - A ground lead runs from the bridge tone casing to the bridge claw (TO BRIDGE CLAW). - The source specifies 500K custom-taper pots. The simulator treats them as linear, so settings between the knob ends are approximate. ## Connections 1. Neck GREEN → Neck volume casing (case, green) 2. Neck BARE → Neck volume casing (shield, bare) 3. Bridge GREEN → Bridge volume casing (case, green) 4. Bridge BARE → Bridge volume casing (shield, bare) 5. Neck volume casing → Neck volume top lug (case, black) 6. Neck volume top lug → Neck tone casing (case, black) 7. Neck .047µF capacitor → Neck tone casing (case) 8. Neck tone casing → Bridge tone casing (case, black): Runs down the right side. 9. Bridge volume casing → Bridge volume top lug (case, black) 10. Bridge volume top lug → Bridge tone casing (case, black) 11. Bridge .047µF capacitor → Bridge tone casing (case) 12. TO BRIDGE CLAW → Bridge tone casing (shield, black): Leaves from the capacitor's casing solder point. 13. Bridge tone casing → Jack sleeve (wire, black) 14. Toggle middle lug (frame) → Jack sleeve (wire, black) 15. Neck volume bottom lug → Toggle top outer lug (wire): Drawn light gray; it passes the bridge leads with a gap (no joint). 16. Bridge volume bottom lug → Toggle bottom outer lug (wire): Drawn light gray. 17. Toggle commons (jumpered) → Jack tip (wire): Drawn dark gray. 18. Neck BLACK → Neck WHITE (insulated, black): Joined and insulated. 19. Neck RED → Neck volume middle lug (wire, red) 20. Bridge BLACK → Bridge WHITE (insulated, black): Joined and insulated. 21. Bridge RED → Bridge volume middle lug (wire, red) 22. Neck volume bottom lug → Neck tone bottom lug (wire): Drawn dark gray. 23. Neck tone middle lug → Neck .047µF capacitor (wire) 24. Bridge volume bottom lug → Bridge tone bottom lug (wire): Drawn dark gray. 25. Bridge tone middle lug → Bridge .047µF capacitor (wire) ## What each position does - Rhythm (neck): Neck pickup (both coils). Source: Neck volume feeds the toggle's neck lug. - Both: Neck pickup (both coils) and Bridge pickup (both coils) in parallel. Source: Both volumes reach the jack together. - Treble (bridge): Bridge pickup (both coils). Source: Bridge volume feeds the toggle's bridge lug. - The source's 500K custom taper is not reproduced: all four pots are simulated with a linear track, so settings between the knob ends are approximate. - The DP103 and DP100 are simulated as generic humbuckers; 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 - In each toggle position, the meter across the jack should read the selected pickup, or both in parallel in the middle. - Turning one volume fully down should mute only that pickup in the middle position. - Each taped black–white joint should read open to ground. ## Source Tinkercaster's own drawing of the DiMarzio diagram Randy Rhoads Sandoval Dot V Wiring, revision 1.
