Updated for new CTS pots and Switchcraft jacks in 2026 production runs, addressing common hum issues and phase problems in stereo wiring.

Stock Wiring Diagram Breakdown

Epiphone Casino uses parallel P-90s with 500k CTS pots, .022uF orange drop caps, and 3-way toggle. Ground to bridge, hot to volume lugs. Common mod: treble bleed circuit for single-coil sparkle.

Advanced Mods: Coil Tap & Phase Switch

Add a push-pull pot for single-coil mode, revealing glassy cleans. Phase reverse via DPDT switch for thinner neck/bridge combos. Use 22awg cloth wire to maintain vintage vibe.

Tools needed: soldering iron (40W), flux, desoldering braid, multimeter. Test continuity before powering on.

Troubleshooting Common Issues

Intermittent signal? Check cold solder joints at pickup leads. Hum? Shield control cavity with copper foil tape. Weak output? Swap to Seymour Duncan P-90s with 4-conductor wiring.

2026 tip: New laminated bodies reduce feedback; rewire ground loop via star grounding.

Stereo Wiring for Bigsby Models

Route neck/bridge to separate outputs using Y-split jack. Balance volumes with dual 500k pots. Ideal for recording direct into Twin Reverb or AC30.
