This kit includes everything you need to wire a Gibson ES-335 or similar guitar. It includes the finest components, from the same suppliers that Gibson has used for years: (2) Capacitor, .022F Orange Drop (1) Jack, Switchcraft 1/4" Mono, Long Bushing (4) Pot, CTS 500k Audio, Low Torque (.500" Bushing Length) (1) Switch, Switchcraft 3-Way Toggle, Short Straight (2) Treble Bleed Kit for Humbuckers (2) Wire, 22 AWG Cotton Push Back w/ Tinned Overcoat, Black (2) Wire, 22 AWG Cotton Push Back w/ Tinned Overcoat, White (2) Wire, 22 AWG Single Conductor Braided (2) Wire, 22 AWG Stranded Silver-Plated Copper, Black PTFE (2) Wire, 22 AWG Stranded Silver-Plated Copper, White PTFE (1) Professional, Fully-Illustrated Wiring Diagram Please note: knobs & switch tip are not included. There are just too many options - we sell 12 varieties of Gibson-style knobs sets. Each includes four knobs plus a Switchcraft switch tip. The knobs will fit these 24-tooth pots correctly, and the switch tip is the right part for the Switchcraft switch included in this kit. Gibson knobs & switch tips fit our parts properly, but imported knobs and switch tips don't. So if you have knobs/tip that came off an Epiphone or other imported guitar (Tokai, Burny, PRS CE, etc), then you're going to need knobs.
