1.1
Drop Blend pot into the neck-side hole. Thread the washer and nut. Finger-tight only — you will tighten after all pots are in.
1.2
Drop Volume pot into the center hole. Push-pull shaft should move freely. Washer and nut, finger-tight. Ensure the DPDT switch body clears the plate.
1.3
Drop Tone pot into the bridge-side hole. Washer and nut, finger-tight. All three pots should have lugs oriented the same way — facing down (toward you when wiring). Tighten all three nuts with a socket wrench once positioning is confirmed.
