Quick Start
Power – Install a 9V alkaline or lithium battery (not included).
Plug in – Use standard ¼-inch shielded instrument cables.
Set input gain – Play hard and try both normal and boost modes.
The clip/batt LED may flash occasionally.
Select an effect – Choose one of the eight modulation effects.
Dial it in – Adjust the level, tone and speed to taste.
Bypass – Step on the footswitch to bypass the effect.

Using Other Effects
When using multiple pedals,
we recommend connecting
them in this order, however
feel free to experiment.

5
Right Side Panel
Input
Plug in with a standard guitar cable to either the left or right input and the
pedal will power on. Or, for stereo operation, connect the outputs from another
stereo effects pedal to both the left and right inputs.
Note: The input for all Fishman AFX pedals is ideal for active pickups and
all soundhole pickups. For passive piezo pickups (no preamp built into the
instrument) we recommend plugging directly into an impedance-matching
preamp first to strengthen the level and maintain proper low frequency content.

Right Side Panel (continued)
Input Gain
This switch lets you quickly set the best operating level for your pickup. Start with
the input gain switch set to normal. When you play hard, the clip/batt LED
should flash only occasionally. If the LED does not flash with hard playing, select
boost. Typically, soundhole pickups will
require a gain boost while onboard pre-
amp systems will use the normal setting.
The pedal is designed to automatically
maintain constant level when switching
between normal and boost positions,
so you will hear no difference in the over-
all output level when setting this control.

Left Side Panel
Output
Use a standard guitar cable to connect either the left or right output to
another pedal, amplifier or mixing board. For stereo operation, connect both
left and right outputs.

Power
Power may be supplied by either a 9V battery (battery compartment under the
pedal) or an AC adapter (sold separately). Insert a plug into either input jack,
and the pedal powers up. To conserve the battery, remove the plug(s) from the
input jack(s) when not in use.
For AC power, use the Fishman 910-R (for 110V) or other suitable 9V adapter. The
adapter must be filtered, regulated and rated for at least 200mA. It must also
accept AC power appropriate for your country. Power-plug requirements: 5.5mm
O.D., 2mm I.D., tip = negative.

Controls
Level
The level control mixes the selected effect in parallel, adding as much or as little
chorus as you want in addition to your direct sound. This means that your tone is
preserved while the effect is blended into it.
Ton e
Use this to add brightness or warmth to the sound of the effect without altering
your direct sound.
Speed
This controls the rate or speed of the selected effect.
For the rotary effect, this knob acts like a slow/fast switch when it is moved either
side of the 12 o’clock position.

Effect Select Knob
AFX • Chorus offers eight popular modulation effects, EQ’d to work well with
the resonances found in acoustic instruments. Be sure to check them all out in
stereo as many can create a very wide, dramatic effect.
Chorus 1
This is a very subtle chorus which adds a light detuning and wide stereo image.
The chorus effects are built from three “voices” (delays) that are constantly mov-
ing and swirling around each other. As you adjust the speed control, the voices
chase around more quickly, resulting in more detuned, or chorused, effects.
Chorus 2
A thicker and more heavily modulated chorus.
Chorus 3
Wide and deep, capable of producing thick to very warbly sounds.

11
Controls (continued)
Stereo Tremolo
When used in stereo, this tremolo sounds more like a traditional panner, mov-
ing the audio source from left to right and back again. When used in mono, this
tremolo has a very sinusoidal, or even, waveshape, reminiscent of classic surfer
songs.
Narrow Tremolo
This is a monophonic tremolo with a characteristic irregular sound much like the
opto-tremolo found on classic ’60s guitar amplifiers.
Flanger
The flanger effect is capable of creating a wide variety of flanging sounds, from
smokey, sweeping ’70s sounds to classic jet plane washes and even heavy under-
water effects. originally created by playing back two identical recordings, slowing
down one or the other by rubbing the flange on the recorder’s tape reel.

12
Controls (continued)
Phaser
This is a classic ’70s modulation effect that adds motion and constantly shifting
harmonics. Like the choruses and flanger, many finely-tuned delays are in con-
stant motion, but spread apart to create wild effects that retain great definition.
Rotary
Simulates the spinning sound and Doppler effect of a rotary speaker cabinet. In
this effect, tone balances between the drum (warm) and horn (bright), while the
speed control mimics the fast/slow switch found on the original amplifier.
Footswitch
When the green light above the footswitch is on, the effect is active. Step on the
footswitch to bypass the AFX • Chorus. When the effect is bypassed, your in-
strument signal passes through an all-analog buffered signal path. This buffered
path provides an incredibly low-noise output useful for driving long cable runs,
such as to a mixing console.

13
Battery Replacement
The clip/batt indicator will light steadily when it is time to change the battery.
Open the battery door underneath the pedal and install a fresh 9V alkaline or
lithium battery. When the clip/batt LED comes on you have approximately one
hour of remaining battery life.
