Level Knob: Controls the overall output level. Unity gain between the bypassed and engaged signals
resides at 12 o'clock on the knob. Turning the LEVEL knob fully clockwise boosts the dry signal
roughly 6dB.
Dwell Knob: Controls the level of the dry signal hitting the spring tank. Turning the up the DWELL
control adds a more overdriven and animated quality to the wet signal. Alternate Function: While
holding down the CONTROL INPUT button on the top of the pedal, the DWELL knob temporarily
controls the DEPTH of the tremolo effect without changing the DWELL amount.
Tone Knob: Controls the equalization of the reverb signal. Turn the knob to the left for a darker
sound and to the right for a brighter reverb signal. Alternate Function: While holding down the
CONTROL INPUT button the TONE knob adjusts the RATE of the tremolo effect.
Effect Switch: Selects between the three spring reverb engines – SHORT, LONG, and TANK. Alternate
Function: While holding down the CONTROL INPUT button the center toggle switch selects between
the three types of tremolo - OPTO, HARMONIC, and BIAS. By default, all three of the spring reverbs
are paired with OPTO Tremolo.
Footswitch: Enables or bypasses the effect. Pressing and holding the footswitch from the bypassed
state also toggles between Standard and Preset Modes. The pedal mode is indicated by the
illuminated green (Standard) or red (Preset) center LED color.
