Congratulations on your Purchase of the Fulltone Analog Stereo

ChoralflangeTM

As a professional musician and studio guitarist, I spent many
years not being able to find a Chorus or Flanger that was good
enough to stay on my pedalboard for any length of time.
All the pedals I tried were either too murky, too hi-fi, distorted
horribly when the strings were hit hard, lacked true bypass, were
too noisy, or lacked the features and flexibility to allow me to
create my own signature chorus or flange sounds.

Chorus can be a wonderful sound, but if you’ve ever tried a Digital
(including digital modeling) unit you might not give it a second
listen. Analog circuits, when done right, can offer unexcelled
warmth and shimmer that augments, instead of detracts from,
your signature sound. Flangers have always gotten a strange
metallic feedback when pushed to extremes, making them little
more than an annoyance and the flanging available in chorus
pedals always seemed at best an afterthought.

After 10 months of extensive research and development we now
offer the Choralflange

TM, which I designed for discriminating

Guitarists and Bassists everywhere. Offering a wide range of
fantastic chorus, flange, and rotating speaker sounds, together
with tons of flexibility, top-notch components and construction, it’s
the first pedal ever to offer a switchable choice between true­bypass or buffered outputs. From the custom aluminum
hammertone-green enclosure, to the Gold-Plated IC sockets, to
the acid etched faceplate, there’s lots of love put into this
thing…Play on!

ChoralflangeTM Features

Mix knob: this sets the balance between straight (unaffected) guitar and the effected
sound. Clockwise (CW) yields more effect, Counter Clockwise, (CCW) more guitar.

Chorus / Flange toggleswitch: chose between the two modes of operation. Both
function in either Mono (1 amplifier) or Stereo (2 amps) operation.

Volume Adj . trimmer: this only affects the volume when the effect ON/OFF footswitch is
in the “ON” mode. Why? Because there can often be a large difference in the level
between the bypassed and “ON” modes depending on your settings, particularly when

operating this chorus in stereo. (Two amplifiers) The Volume Adjust is crucial for
getting the right balance so that there is not a Boost or Cut unless you desire.

Delay Time knob: allows for Delay lengths ranging from 1 to 50 milliseconds. The
length of Delay times determines the amount of Vibrato present in the chorus, and the

affected frequencies of both the chorus and the flange modes.
Depth knob: this controls the saturation or “wetness” of the “ON” sound, and along with

the Mix knob, gives this pedal the ability to sound vintage-thick, extremely transparent,
or anything in-between.

Narrow / Wide toggleswitch: set to Narrow, the affected frequency bandwidth will be
approximately 1 Octave. Set to Wide, the affected frequency will be approximately 2
Octaves. This range is also affected by the chosen Delay Time setting.
Rate knob: controls the speed of the modulation and is reflected in the flashing LED
positioned next to it. Slower speeds are generally used for Chorusing and Heavy
Flanging sounds. Faster speeds are generally used for Leslie and wild chorus/vibrato
sounds
Input Jack: plug guitar or Bass into this, remember to unplug when not in use to

prolong Battery Life. Warning: this device is designed for “normal” output Pickups and

not Super-Hi-Gain ones like the “LiveWires”, EMG85’s, etc. Use of these could overload
the input of the Choralflange. Lower gained PU’s equals better tone anyway IMHO.

Output 1: use this for mono (single amp) operation.
Output 2: use this only in conjunction with Output 1 when stereo operation is desired.

Caution! Always make sure there are no grounding problems when using multiple amp set-ups.

Failure to maintain proper ground can cause serious injury or even death!

DC Jack: this is a standard 2.1mm Barrel Jack connector, and is configured (like most
effects) with the Center Pin being Negative. It is HIGHLY recommended that you use
only the Fulltone FPS-1 because it is regulated and the optimum tones in this pedal are
achieved with exactly 9.0 volts…fresh batteries are often 9.5+volts and the flanging
sounds may be affected.
Internal Adjustments : there are NO internal user adjustable parameters in this pedal.
There are trimmers that are set by us and are not to be touched, you will ruin the pedal.
