How To Get A "Fat Head"
"The simple way to get more sustain,
overtones and balance from any guitar..."
A FATHEAD is a simple idea that works on the principle that
increasing the mass of a guitar's headstock will increase the duration
of string sustain The addition of FATHEAD effectively triples the mass
at the headstock of any guitar or bass it's attached to. We know what
happens if we make the body thicker and heavier, as an example compare a
Gibson Les Paul to an SG for sustain and tonal response. The heavier
Les Paul has more sustain and a fuller tonal range because the body has
twice the mass.
