7.1.7 MODULATION EFFECTS (MOD)
The FX770 contains seven different types of modulation effects: Stereo Chorus, Stereo Pianger, Symphonic, Rotary
Speaker, Auto Pan, Tremolo, and Resonator. Each of these effects are capable of creating, or adding, dramatic
textures to your sound.
Chorus
Embraced by modem and vintage guitarists alike, Choras may be the most widely used modulation effect today. Here
you’ll find a versatile and great sounding Choras with lots of control, so you can decide what kind of Chorus make
you happy.

Notes:
Modulation Speed
Pitch Modulation
Amp Modulation
Sets the speed of the LFO to produce the modulation wave, thus changing the modulation speed of the
Chorus effect.
Controls the depth of the Pitch modulation.
Controls the depth of the Amplitude modulation.
Sound Image Width Determines the stereo image of the output.
Mix Balance Mixes between the Dry signal and the Chorus effect (Setting this to 100% will produce only the choras
effect.)
Output Level Overall Level of this Effect Block.
Delay Time
LFO Wave Form
Filter Sets the delay time of the Modulation.
Determines the type of LFO Wave Form: Triangle (TRI) or Sine (SIN).
A “tone control” for the Choras.
