With 43 AWG on the top coil with 44 AWG on the bottom coil. By turning the tone knob down the signal runs through a capacitor, and as a result, only the larger (bass) coil underneath is activated. This gives the instrument a thick, solid lower bass tone. By turning the knob up, the upper (treble) coil gradually gets blended in to the already low end bass sound. As the tone knob gets turned up more, the treble coil gets more prominent, while the lower bass coil begins to dissipate. With the tone knob full up, the larger bass coil underneath, along with the capacitor, gets faded out altogether, resulting in a very trebly-midrange sound.
