5 Control Wiring Harness. 2-Volume, 2-Tone, 1-Mixer and 1- 3-Way Selector Switch. Used on most guitar models built to vintage specs with 250K volume and 500k in all other positions. Utilising Orange Drop Tone Capacitors.

Some companies making aftermarket wiring assemblies have adopted a different layout and connected the tone capacitors to the volume controls instead of the selector switch. By doing this they have introduced a flaw which is that when a pickup is switched out of circuit, both tone controls are still connected and either will affect the connected pickup especially noticable when both volume controls are set to maximum and a muddy sound will be the result.
