I hear a symphony, and so can you.
The Alexander Fever Pitch represents a quantum leap forward for effects pedals, combining a
four-voice pitch shifter with a exible effects section.
Using the pedal is pretty simple: plug your instrument into the INPUT jack and your amplier
or other effect into the LEFT / TRS jack, power up the pedal with 9V 250mA or more, and turn
some knobs. You’ll be rewarded with expansive textures Fever Pitch’s FXCore DSP processor
and our own custom microcontroller interface.
This manual contains full technical details on the operation of this pedal.
For more information regarding rmware updates, update tools, and
software integration, please scan the code in this section to visit our
website.
BASIC OPERATION

more info!
INPUT: Instrument input. Defaults to mono, may be set to TRS Stereo or TRS Sum using
the Global conguration menu.
RIGHT: Right stereo output. This output may be phase-inverted in the Global conguration
menu to match the output phase of your amplier setup.
LEFT / TRS: Main output. Defaults to mono output, may be set to output the left side of the
stereo output using the Global conguration menu. May also be used as a TRS
stereo output (disables the RIGHT jack) if the next effect or input is TRS stereo.
DC 9V: Center-negative, 2.1mm ID barrel jack for DC input. The pedal requires a
minimum of 250mA to operate, higher current supplies are acceptable. Do not
power the pedal from a source greater than 9.6V DC.
USB: USB mini-B connector for USB MIDI or rmware updates
MULTI: User congurable jack, used for Expression pedal (TRS only,) remote footswitch,
or MIDI input / output (requires converter unit or adapter cable.)

ABOUT ALEXANDER PEDALS
Alexander Pedals builds hand-crafted eects pedals in Garner, North Carolina. Each Alexander Pedal is
meticulously voiced and tweaked by our sonic scientists to achieve sounds that are both instantly familiar yet
completely unique.
Alexander Pedals are designed by Matthew Farrow and a group of trusted players, builders, and friends.
Matthew has been building guitar pedals since the late 1990s, rst with Pharaoh Ampliers, and now with
Disaster Area Designs. Matthew has designed some of the most innovative eects units on the market,
including some big names he’s not allowed to tell you about.
Alexander Pedals was started for two reasons - to make great tones, and to do good. The great tones part you
probably have some idea about. As for doing good, Alexander Pedals donates a portion of the prots from
every pedal sold to charity, whether you buy from us or our dealers. Matthew’s younger brother Alex passed
away in 1987 of a form of cancer called neuroblastoma. Alexander Pedals honors his memory by helping in the
ght to end childhood cancer.

CONTROLS & DISPLAY
Fever Pitch is a pretty complex pedal under the hood, but we worked hard to make sure that it’s
easy to drive.
We combined a simple user interface with a high-resolution OLED display to get you the
maximum tweakability with the minimum frustration.
The lower left knob is an endless rotary encoder with push switch. Turn this knob to navigate
between pages of the user interface, each page has a new group of effect controls to tweak.
You can tap the encoder to switch between the delay and reverb modes, or hold it to access the
Setup, Preset Save, or Scale Save menus.
The other ve knobs adjust the parameters on the current page, and the parameter names and
values are shown on the display.
The display shows the current function and position of each knob, as well as the sound mode,
preset name, and page name. If you’re using an expression pedal, the display will also show
the pedal position while it’s moving.
PRESETS
How do you make quick changes on a pedal that has 9+ knobs? PRESETS. Fever
Pitch allows you to save up to 32 presets that contain the entire state of the pedal.
Loading a preset recalls all knob positions, sequence steps, sequencer settings, and
expression pedal mappings.
To load a preset, hold the BYPASS / PRESET footswitch. You can set the number of
available presets in the Setup Menu, from 1 to 8. You can also set the pedal to access
the upper banks of presets (9-16, 17-24, 25-32) in the same menu. This allows you to
use multiple banks of presets for different gigs, bands, instruments, whatever you like.
You can also use an external MIDI controller to load any preset from 1-32, regardless of
how the Setup Menu is congured.
To save a preset, rst use the pedal knobs to tweak the sound, then hold the Page
knob. Press and hold the BYPASS / PRESET footswitch to enter the save menu.
If you want to save to the current preset, you can just hold down the BYPASS /
PRESET footswitch again. If you prefer to rename the preset, turn the Page knob to
select a character in the name and then tap the Page knob to edit that character. Use
the Page knob to select the preset number and edit to change the save location.

Conducting the symphony
Fever Pitch is an exciting an unique device, made up of a customized chain of cascading eects modules. Each page of the user interface allows you, the player, to interact with dierent parts of the pedal to tailor
the sound as you see t.
The basic structure of the Fever Pitch eect is: Input -> Four Stereo Pitch Shifters -> Reverb / Delay -> Stereo Tremolo / Pan -> Stereo Chorus / Vibrato
Turn the knob to the left of the display to select a new page of controls - the small boxes at the bottom of the display indicate which page you’re currently accessing. The display will then change to show the
various controls available on the current page, as well as their settings.
MAIN PAGE
Sets the volume levels for each of the
four pitch shift voices, as well as the
volume level for the dry / unaected
input signal.
TUNING PAGE
Sets the pitch tuning for each of the
shift voices. Turn the lower-right knob
to access preset or custom tuning
scales.
PAN PAGE
Sets the stereo panning level for each
of the four pitch shift voices, as well as
the dry signal panning. Pan controls
are disabled if output is set to mono.
reverb PAGE
Sets the parameters for the built-in
reverb eect. Tap the mode knob to
replace the reverb with a delay eect.
mod.fx PAGE
Sets the parameters for the built-in
stereo tremolo / pan and chorus
eects. Turn the lower-right knob to
select the tremolo or pan mode.
misc PAGE
Sets master volume and tone controls,
as well as the ramp rate and ramp
trigger type. The lower-right knob
enables “detuning” for any pitches set
to unison.

REVERB AND DELAY
We’ve incorporated a exible time-based eect section to ll out your sound with Fever Pitch.
The pitch shifters and dry signal all feed a reverb and delay engine with stereo capabilities.
Tap the PAGE knob to switch between Reverb and Delay modes, as shown on the REVERB /
DELAY page.
PITCH SHIFTING
Dialing in usable musical intervals can be challenging, so we’ve given you a little help.
Navigate to the TUNING page and turn the lower right knob to select from one of our
preset scales. The intervals listed below are in semitones from your input pitch.
UNI: 0, 0, 0, 0 MIN1: 0, +3, +7, +12
OCT1: -24, -12, +12, +24 MAJ2: -12, -7, 0, +4
OCT2: -12, +12, -12, +12 MIN2: -12, -7, 0, +3
O5TH: -12, -7, +7, +12 MAJ7: 0, +4, +7, +11
5THS: -7, 0, 0, +7 MIN7: 0, +3, +7, +10
MAJ1: 0, +4, +7, +12 OCT5: -12, -7, -12, -7
You can also create your own custom scale that will be available for use in any preset.
Turn the lower right knob until one of the User scales is shown (USR1-4,) then tweak
the intervals. Hold down the PAGE knob, then keep it held until the scale saved
message appears.
Finally, don’t forget you can just manually input any pitches you like! You don’t need to
use the scales at all, they are just here to help.
Now that we’ve seen the big picture, let’s explore some of the hidden details in Fever
Pitch: the heart of the pedal is the pitch-shifting section, with four independent voices.

MODULATION EFFECTS
We’ve also packed two independent modulation eects into the output section of Fever
Pitch. Use the MOD.FX page to dial them in.

PAND
The tremolo / pan eect has four dierent modes:
TREM: tremolo eect on wet signals, both left and right channels have the same modulation
PAN: panning eect on wet signals, left and right channels have opposite modulation
TR+D: tremolo eect on wet and dry signals, this produces the most intense tremolo
PN+D: panning eect on wet and dry signals, this produces the most intense panning.
The modulation eects do not respond to tap tempo or MIDI clock.

EXPRESSION AND RAMPING
Fever Pitch will smoothly blend between the two knob settings as you move the
expression pedal. You can map any of the effect knobs to the expression pedal, other
than a few controls that don’t have linear functions like tap division and tremolo mode.
If you prefer to have controls that aren’t affected by the expression pedal, simply set
them with the pedal heel down, then gently “wiggle” the knob with the pedal at toe
down. This will set the same values for heel and toe and those knobs won’t change as
you sweep the pedal.
The MultiJack input is factory-calibrated for most common expression pedal types,
but you can also adjust the range using the conguration menu. Tweak the EXP LO
parameter to set the heel down value and the EXP HI parameter to calibrate the toe
down position.
You can also use the Ramp function to automatically move between expression
positions. Use the RAMP knob to set the speed of the ramp, and the TRIG knob to set
the trigger mode. Hold the Tap / Ramp footswitch to re the ramp.
TOGG ramp will alternate between positions when you hold the footswitch
MOM ramp will move from heel to toe when you hold the footswitch, and return
when you release it.
REPT ramp will start when you hold the footswitch, and will automatically move
from heel to toe and back until you hold the footswitch again.
Hold the PAGE knob on the MISC page to reset the ramp / expression settings.
Connect a TRS expression pedal to the MultiJack to control any or all of the pedal
parameters remotely.
Fever Pitch requires a TRS expression pedal, sleeve = 0V (common,) ring = 3.3V, tip
= 0-3.3V. You can also use an external control voltage connected to tip and sleeve, as
long as it doesn’t exceed 3.3V.
If you’re using a MIDI controller, you can send MIDI CC 100, value 0-127. 0 is the
same as full heel setting, 127 is toe setting.
To map expression pedal values to pedal settings, rst set the expression pedal to the
heel setting then turn the pedal knobs. Then sweep the expression pedal to the toe
setting and turn the knobs again.

STEREO ROUTING
Fever Pitch was designed to work in a stereo context - everything centers (no pun intended)
around its exible routing and panning controls. We’ll cover how all the various stereo
modes work so you can pick the one that works best with your rig.
To set the stereo mode, enter the setup menu and navigate to STEREO. The pedal will
recongure its inputs and outputs as you step through the menu, and once you’ve set it as
you like just hold the PAGE knob to save.
MONO INPUT
Standard mono input.
Use this for mono input with full
stereo output.
input sum
Input is summed L+R from TRS,
output is full stereo.
stereo
Input is stereo from TRS, output is
full stereo.
Use this if the previous device in
chain has stereo output.
MONO I+O
Input is mono, output sets all pan
controls to center for dual mono.
Use this if using the pedal strictly
with one amp, prevents signal loss
with wide pan settings.
sum mono
Input is mono summed from TRS,
output sets all pan controls to
center for dual mono.
Use this if previous device in chain
is stereo but only one amp is
connected.

MIDI
Fever Pitch features full and comprehensive MIDI implementation. Every single function and
knob may be controlled by MIDI.
The pedal will accept USB MIDI at any time, or may be used with 1/4” MIDI by setting
M.JACK = MIDI in the Global conguration menu. The pedal will respond to MIDI messages
sent on the channel set in the Global menu only.
The 1/4” MIDI input is compatible with the Neo MIDI Cable, Neo Link, Disaster Area MIDIBox 4,
5P-TRS PRO, or 5P-QQ cables. Most other 1/4” compatible MIDI controllers should work, the
pedal requires pin 5 connected to TIP and pin 2 connected to SLEEVE.
