Some 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.
