Yamaha FX770 - Manual (Page 49)

Section 7: Reference
Stereo Flanger
Whether it’s a subtle swoosh or the exaggerated “jet fly-by”, the Flanger has a unique voice in the modulation world.
Created by accident in the 60’s, and faithfully produced in the 90’s, the Stereo Flanger of the FX770 is a wonderful
effect!
Type 2: FLG (Stereo Flanger)

Sets the speed of the LFO to produce the modulation wave, thus changing the modulation speed of the
Flanging effect.
Controls the depth of the Modulation.
Sets the delay time of the Modulation. Controls the flanger’s sweep range.
Determines the amount of feedback. Controls the volume level of the flanger’s sweep.
Determines the stereo image of the output.
Mixes between the Dry signal and the Flanger effect (Setting this to 100% will produce only the chorus
effect.)
Overall Level of this Effect Block.
Determines the type of LFO Wave Form: Triangle (TRI) or Sine (SIN).
A “tone control” for the Flanger.
