The controls
FEEDBACK
Use the FEEDBACK knob to control the amount of feedback of the short modulated delay that causes
the Flanging effect. Turn the knob counter-clockwise to get negative feedback and clockwise to get
positive feedback. Where the positive range gives a traditional studio-type feedback the negative range
gives more extreme and “tube-like” sound. Try them out! 12 o’clock position is neutral = no feedback.
Notice that too high settings might introduce internal feedback, resulting in a squealing noise that in
most cases is unwanted in flanging effects.
SPEED
Use the SPEED knob to set the speed of the effect.
DEPTH
Use the DEPTH knob to set the intensity of the effect. The more you turn the knob clock-wise, the more
“out of tune” the modulated part of the signal is.
DELAY TIME
Typical delay values for flanging effects are around 1-2 ms whereas Chorus effects occur with delay
times around 10 ms. Short delay times give very intense, “jet engine”-type sounds with plenty high-end
frequencies. Longer delay times give the slightly darker more “tube”-type sounds.
