The Hum Filter effect is effective in removing the A.C. line noise from a signal.
Parameter
The Fq (Frequency) parameter selects between an AC line frequency. Select either
or (European).
The Coil Tap effect is a special digital filter which can be used to emphasize or de-emphdsize harmonics.
Parameters
When the phase parameter is set to a positive number, the
amount of harmonics being emphasized. When the phase parameter is set to a negative number,
the harmonics are de-emphasized. Range is
Ph
The (Phase) parameter is used to select the emphasis or de-emphasis of harmonics. Setting the
Phase to a positive number will emphasize harmonics, while setting the Phase to a negative
number de-emphasizes the harmonics. Range is
The Exciter effect uses a "distortion technique" to add harmonics.
in a distorted sound, but instead produces an exciter effect.
Parameters
Dr
The (Drive) parameter setting determines the amount of harmonics added. Range is 0 (no
harmonics) to 100 (maximum harmonics).
Tu
The (Tune) parameter controls the amount of emphasis. Range is O.lK (excites lower
frequencies) to
The (Type) parameter is used to select between three different distortion types which product
three different sounds. Range is
type 3 adds even and odd harmonics.
Ba
The (Balance) parameter is used to set the balance. Range is 0 (direct) to
