Alexander SKY FI, Manual

Bathe your signal in an excess of echoes, a 

deluge of delay, and a surfeit of shimmer.  

All of the ambience you desire is a footstep 

away.

Controls:

Reverb

 — Adjusts the mix and decay of the reverb engine.  Turn while holding the 

footswitch to adjust the delay mix level.

Delay

 — Changes the delay time for the delay engine.

Repeat

 — Controls the feedback and repeats of the delay engine.  Rotate counter-

clockwise for dark, filtered repeats.  Rotate clockwise for bright repeats.

Mix

 — Rotate counter-clockwise for more dry signal,clockwise for more wet (delayed) 

signal.  Equal mix is found with the control centered.

Mode Toggle:

Wash

 — Combines an 800ms delay with our slow-building reverb engine.  Holding the 

footswitch initiates reverb sustain.

Gleam

 — Adds an upper octave partial to the reverb effect, holding the footswitch 

swells in a pronounced shimmer.  Maximum delay time in this mode is approximately 

640ms.

Echo

 — Slow-build reverb plus delay, holding the footswitch reduces the reverb slightly 

and forces the delay into oscillation.  Warning - extremely loud oscillation and / or 

total collapse of your signal may occur!

HOLD Function:

The Sky Fi has a unique feature - the bypass footswitch integrates with the reverb and 

delay engines.  Hold the footswitch to shift the reverb or delay engine into a feedback 

mode.  In Wash and Gleam modes, the Hold function increases the Reverb time 

and mix to an infinite setting.  In Echo mode, the Hold function increases the Delay 

feedback to maximum levels.

The Hold function has two options:  

Infinite

 allows new notes to be added to the held 

signal.  

Freeze

 routes the dry signal around the held notes so that you can play over 

the frozen notes without changing their harmonic content. To switch between the two 

modes, hold the bypass switch while powering on.  The LED will blink once for Freeze 

or five times for Infinite.  The pedal remembers the last setting.  

Bypass Switching:

The Sky Fi features a buffered bypass with “trails,” so that the reverb and delay will 

continue to repeat when the pedal is bypassed.  The Sky Fi features an analog dry 

signal path.  If the Sky Fi is set to Infinite mode, you can engage the pedal and the 

Hold function by holding the footswitch while in bypass.  Release the footswitch to 

return to bypass mode.

Wet / Dry Output:

The Sky Fi allows the player to separate the wet and dry signals at the output jack.  

Insert a standard mono patch cable into the jack to use as a traditional guitar pedal 

- the output will contain both wet and dry signals as determined by the Mix knob.  If 

a stereo / TRS cable is connected, the Sky Fi will place a buffered dry signal on the 

“ring” of the jack and a mix of wet and dry on the “tip.”  Set the Mix control fully 

clockwise to have complete wet / dry separation.  The Sky Fi will send the dry signal 

to both outputs when bypassed.

Power Supply:

The Sky Fi requires a 9V DC power supply with 

a 2.1mm pin, center negative.  The Sky Fi is not 

designed to be powered on supplies higher 

than 9V and does not use a battery.  The Sky Fi 

should work fine on a multi-pedal “daisy chain” 

connector, but if you encounter excessive noise 

or hum try a separate power supply.

Reverb.  Delay.  Repeat.
