  • VOLUME (Green LED): The VOLUME knob adjusts the output 
level, ranging from zero gain to +6dB. Unity gain is found at 
roughly 12 o’clock.
  • LoRETAIN (Red LED): The LoRETAIN function adjusts the 
frequency below which the original signal remains unaffected. 
This function is especially useful for bass players—increasing the 
LoRETAIN insures a solid low-end foundation while maintaining 
the characteristics of the chosen effect. Guitarists may also find 
it useful—if the FEEDBACK control is cranked up, increasing 
LoRETAIN will prevent excessive volume fluctuations in the 
lower frequencies.
  • TREMOLO (Green LED): The TREMOLO knob adjusts amplitude 
modulation. Unlike traditional tremolo, the Orbital Modulator’s 
amplitude modulation is embedded within the flanger, phaser, 
and chorus effects, creating a wide range of very unique and 
three-dimensional modulation effects. But the TREMOLO func-
tion, if dialed in correctly, will also create sounds reminiscent 
of classic amplifier generated tremolo or replicate the sound 
of a rotating speaker (see the EFFECT TYPES section for more 
detail).
