# DiMarzio Ernie Ball Music Man Eddie Van Halen 2 wiring: two pickups, on-on-on selector board, volume Canonical page: https://guitarwiring.app/wiring-diagrams/dimarzio/evh-2-ebmm-board-on-on-on-selector-volume Neck pickup · Bridge pickup · DPDT on/on/on mini switch (EP1108) on the EBMM board · 500K volume DiMarzio's Ernie Ball Music Man Eddie Van Halen 2 wiring for two-conductor pickups: each pickup's WHITE goes to the selector board, its BLACK and BARE to the board's ground copper, and the board feeds a 500K custom-taper volume and the output jack. There is no tone control. Drawing: https://guitarwiring.app/wiring-diagrams/dimarzio/evh-2-ebmm-board-on-on-on-selector-volume.svg (back of controls) ## Parts and values - Neck pickup (2-conductor stand-in): NECK PICKUP (WHITE, BLACK, BARE); generic (Single-coil pickup (two-conductor)) - Bridge pickup (2-conductor stand-in): BRIDGE PICKUP (WHITE, BLACK, BARE); generic (Single-coil pickup (two-conductor)) - EP1108 on-on-on selector on EBMM board: Selector on the EBMM board (named 'DPDT MINI SWITCH - 3 POSITION (ON/ON/ON) EP1108' on DiMarzio's EVH Wiring\_Update\_FNL\_v1 revision of this sheet); compatible example (DPDT Mini-Toggle (on-on-on)) - Volume 500K custom taper: VOLUME 500K CUSTOM TAPER POT EP1201; 500k; compatible example (CTS 500k Audio Pot) - Output jack: OUTPUT SWITCHCRAFT® OUTPUT JACK (2-CONDUCTOR) EP1301; compatible example (Switchcraft \#11) - Bridge ground: TO BRIDGE GROUND; generic (Bridge ground wire) ## Specific to this wiring - Sheet title: 'Ernie Ball® Music Man® Eddie Van Halen 2'. 'This wiring is based on the original 2 conductor pickups. The current pickups are now 4 conductor.' - This sheet does not name the selector and prints no position legend. An earlier DiMarzio revision of the same sheet (EVH Wiring\_Update\_FNL\_v1, (c) 2020) labels it 'DPDT MINI SWITCH - 3 POSITION (ON/ON/ON) EP1108' and draws each row's two lugs jumpered. On this sheet the same switch sits on a board: each row's two switch-pin slots are joined by a trace to one solder pad on the left. - The top-left pad takes the bridge WHITE, the middle-left pad feeds the volume, and the bottom-left pad takes the neck WHITE. The three right-hand pads are one ground copper shape: the top pad takes the bridge BLACK and BARE, the bottom pad the neck BLACK and BARE, and the middle pad is wired to the volume casing. - Neither sheet says which lever direction is position 1. The positions here are named by function from the catalog EP1108 contacts: position 1 = neck, position 2 = both pickups, position 3 = bridge (the catalog EP1108 HH\_SELECTOR variant). - The volume's top lug is wired to the volume casing and on to the jack sleeve. The output jack is a 'SWITCHCRAFT® OUTPUT JACK (2-CONDUCTOR) EP1301'; 'TO BRIDGE GROUND' ends on the jack sleeve. - The pickups are drawn unnamed ('NECK PICKUP', 'BRIDGE PICKUP') with WHITE, BLACK and BARE leads. ## Connections 1. Board top-right pad (bridge BLACK) → Board bottom-right pad (neck BLACK) (wire): Board ground copper: the three right-hand pads are drawn as one shape joined through narrow necks. 2. Bridge BARE → Board top-right pad (wire, bare) 3. Neck BARE → Board bottom-right pad (wire, bare) 4. Board middle-right pad → Volume casing (case, black) 5. Volume casing → Volume top lug (case, black) 6. Volume top lug → Jack sleeve (wire, black) 7. TO BRIDGE GROUND → Jack sleeve (wire, black) 8. Neck WHITE → Board bottom-left pad (wire, white): Drawn broken where it passes the bridge leads. 9. Bridge WHITE → Board top-left pad (wire, white) 10. Board top row, first switch pin → Board top row, second switch pin (wire): Board trace, drawn as the copper joining the row's pins and pad. 11. Board middle row, first switch pin → Board middle row, second switch pin (wire): Board trace, drawn as the copper joining the row's pins and pad. 12. Board bottom row, first switch pin → Board bottom row, second switch pin (wire): Board trace, drawn as the copper joining the row's pins and pad. 13. Board middle-left pad → Volume bottom lug (wire, white) 14. Volume middle lug → Jack tip (wire, gray) ## What each position does - Position 1: neck: Neck pickup (2-conductor stand-in). Source: No legend printed; named by function from the EP1108 contacts. - Position 2: neck + bridge: Neck pickup (2-conductor stand-in) and Bridge pickup (2-conductor stand-in) in parallel. Source: No legend printed; named by function from the EP1108 contacts. - Position 3: bridge: Bridge pickup (2-conductor stand-in). Source: No legend printed; named by function from the EP1108 contacts. - Neither this sheet nor the v1 revision says which lever direction is position 1; the lever mapping is by function. - The switch contacts are the catalog EP1108 table; the v1 sheet names the part but prints no contact chart. - The source's custom-taper volume is not reproduced: the pot uses the catalog pot's taper, so settings between the knob ends are approximate. - Each pickup is simulated as a generic two-conductor pickup; the humbucker's hum-cancelling construction and its resistance are not modelled, so no numeric meter readings are given. ## Check before plugging in - Position 1: continuity from jack tip to sleeve through the neck pickup only. - Position 2: both pickups in parallel between tip and sleeve. - Position 3: continuity through the bridge pickup only. - With the volume at zero, tip and sleeve read as a short in every position. ## Source Tinkercaster's own drawing of the DiMarzio diagram Eddie Van Halen Original Wiring without Toggle Switch, revision 2.
