10 | Controls: Knobs
• 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).
