Graph Tech Ghost - Manual (Page 67)

You can add a tone control to the Acousti-Phonic volume circuit to
attenuate the high frequencies, the same as you would on your
magnetic circuit. Be forewarned that a lot of players think they
will need this, but discover they never use it because they prefer
the EQ’d acoustic sound the way it is. Try your ghost® system first
without the added tone pot, and install it if you really need it.
