Parts

Two kilograms of filament are required for a complete body. PET-CF is preferred for ease of use, dimensional stability, and material strength.

A flexible marine-grade epoxy that handles vibration and stress without cracking. One kit has enough epoxy for multiple Relay bodies.

Necks with identical listed specs can vary meaningfully. Budget time for fitting and check compatibility before ordering.

The Relay body is designed around a fixed string-through hardtail bridge. Tremolo bridges are not compatible with the current body.

These press into the back of the body and receive the neck bolts. Install them after confirming neck alignment because they are permanent.

The string ferrules anchor the strings through the back of the body.

Locking tuners make restringing faster and improve tuning stability while the setup is being dialed in.

Relay uses standard strap button mounting locations.

Three packs are recommended because setup work can sacrifice a string or two.

These secure the rear cavity cover after electronics installation.

These secure the truss rod cover on the headstock.

Knob fit depends on the pots selected for the model.

Concentric pots need stacked knobs: a small upper knob and a larger lower knob for each pot. Reef Plus uses these instead of the standard knob set, so skip the standard knobs. Order one set per pot.

The lipstick subsystem in Relay Reef and Relay Reef Plus: one in the neck, one in the middle. Each is around 6K. Order two; the price shown is for one.

Moderate-output bridge humbucker for Relay Lipstick, Relay Reef, and Relay Reef Plus. In Lipstick, high-output pickups overwhelm the lipstick layer. In the Reef models, it is the heavier voice family and should contrast clearly with the lipsticks; a tamer humbucker narrows that contrast.

One concentric pot for the lipstick side and one for the humbucker. Each has a volume deck and a tone deck on separate shafts. Allparts lists EP-4586-000 with a 3/16-inch upper shaft and a 1/4-inch lower shaft. Concentric pots have not been test-fitted in a Relay body yet; check the control-hole size and cavity depth before ordering. Order two; the price shown is for one.

Selects the lipstick side only: neck lipstick, both lipsticks, or middle lipstick. Relay Reef and Relay Reef Plus use both poles so that the two lipstick hots never share a contact. The humbucker does not go through this switch.

Relay Lipstick, Relay Torch, and Relay Velvet all specify a 22 nF (`0.022 µF`, `223`) master-tone capacitor. Relay Reef Plus needs **two** 22 nF capacitors, one for each side's tone. The Torch Edge Contour also needs a **separate** 2.2 nF (`222`) capacitor and 150 kΩ resistor, wired together as shown in its wiring guide. Do not use the 2.2 nF contour capacitor in place of the 22 nF tone capacitor.

The listed part is a Switchcraft-style jack that fits the Relay body cavity.

Used for control-cavity wiring and ground connections.

Used to shield the control cavity. Conductive adhesive is required so overlapping pieces maintain electrical continuity.
