Knobs and Switches - 4-Stage Phaser Controls
SPEED
Adjusts the LFO rate.
MIX
Adjusts the balance of the dry signal
and the phase-shifted signal from mild
phasing at min to 100% wet at max.
Strongest phasing effect occurs with knob
set at 12 o’clock (50/50 mix).
DEPTH
Adjusts the LFO range. A deeper phasing effect
is achieved as the knob is turned clockwise.
ON
Engages the 4-Stage phaser circuit,
independent of the 6-Stage phaser. RED ON
LED indicates that the 4-Stage phaser is
engaged. The LED pulses in time with the
selected SPEED when engaged.
SWEEP
Selects the style of the 4-Stage phaser.
classic: traditional rising and falling LFO* voicings that change in
character as the DEPTH knob is adjusted
barber: continuously rising or falling LFO. Direction is set via live
edit function (See page 10 for details.)
env: touch sensitive envelope phasing effect with range set by the
SPEED knob and sensitivity set by the DEPTH knob
NOTE: *An LFO is a low frequency oscillator. It is used to modulate
the filters that create the phasing effect.

SPEED
Adjusts the LFO rate.
VOICE
Sweeps smoothly from pure phaser
voicings on the left to flanger tones past
12 o’clock and chorus tones on the right.
DEPTH
Adjusts the LFO range. Higher settings
result in more dramatic phase and/or time
modulations as set by the VOICE knob.
ON
Engages the 6-Stage phaser circuit,
independent of the 4-Stage phaser. RED
ON LED indicates that the 6-Stage phaser
is engaged. The LED pulses in time with
the selected SPEED when engaged.
RESONANCE
Selects from three settings of regeneration that add color and
intensity.
off: smooth response
mild: enhanced frequency peaks
strong: prominent frequency peaks
NOTE: When both the 4-Stage phaser and the 6-Stage phaser are
disengaged, the bypass is either Buffered Bypass or True Bypass
depending on the selected mode. (See page 14 for details.)

Strymon MiniSwitch.
(See page 19 for details.)
Tap mode: Allows you to control the SPEED of the 6-stage phaser
with TAP tempo using a Strymon MiniSwitch.
MIDI mode: Allows for the selection of three presets using a
Strymon MultiSwitch Plus. Full MIDI functionality is available by
sending MIDI Program Change messages via 1/4" MIDI connection
using a Strymon Conduit or MIDI EXP cable. Up to 300 presets are
available via MIDI.
(See page 22 for MultiSwitch Plus or page 23 for MIDI.)

release the footswitch.
VOICE knob selections:
Series: GREEN (default) - Output of the 6-Stage phaser feeds into the
4-Stage phaser when both sides are engaged.
Parallel: BLUE - Output of both the 4-Stage and 6-Stage phasers are
mixed to the outputs while maintaining stereo independence of the
LEFT and RIGHT signals.
Split: RED - Sets both the 4-Stage and 6-Stage phasers as mono
effects that are sent to separate outputs. Output of the 4-Stage phaser
goes to OUT L, and output of the 6-Stage phaser goes to OUT R.
(For stereo output connections only.)
Turn the VOICE knob
