Hot Hand Theory of Operation
While it is certainly possible to use Hot Hand without much technical back-
ground, a few words about how it works will allow you to quickly understand
how hand position and hand motion impact the sound.
The Hot Hand sensor senses acceleration. This means that both hand
position and hand motion will cause the Hot Hand to react and send signals
to the control box.
Hand Position
Since gravity is an acceleration, the Hot Hand is always measuring the pull
of the Earth’s gravitational force. To illustrate this, try strumming a chord
and pointing your hand with the sensor attached straight at the ground. By
bending your arm at the elbow, slowly move your forearm up until your hand
is pointing at the ceiling. You should hear the filter sweep from low to high
following the position of your arm. When the
INVERT light is on, the opposite
will be true and the same gesture will sweep the filter from high to low. You
don’t need to move your entire arm to accomplish this. The same effect can
be achieved changing your hand position by bending at the wrist or by leaning
back and moving your hand and the guitar together. Hand position can range
from subtle movement to the not so subtle. If subtlety is not your thing, dra-
matic motions will open the door for showmanship as your hand shapes the
sounds from your guitar. We must point out that the Hot Hand will respond
differently in Outer Space!
When you are using hand position and larger hand or arm motions to control
the Hot Hand, we recommend turning the
MOTION knob towards FLAIL . This
will prevent the Hot Hand from responding to small variations and sounding
too “jittery”.
Hand Motion
In addition to measuring gravitational force, the sensor also measures
movement. The more the hand moves, the more the signal will change. To
illustrate this, strum a chord and shake your hand quickly. You should hear
the filter sweep back and forth following your hand motion. Experiment with
moving your hand in different directions and at different speeds to find the
method that works best for you. Use the
MOTION knob to control how quickly
an effect will respond to your hand motion. In the most sensitive position
(PICK) the Hot Hand will detect even the slightest motion of the picking hand
and the result will sound like an auto-wah. In the STRUM position, the Hot
Hand will react more slowly. Try strumming some chords normally and listen
to how the Hot Hand reacts.

Saving Presets
The PRESET feature of this product has been designed to be simple. This
product allows you to save 4 different configurations so that they may be eas-
ily recalled from the standing position. When you receive your product from
the factory, we have selected what we think are 4 useful configurations. You
may either keep these or replace any of them with your own settings. Should
you wish to return to the original factory presets, the configurations and other
ideas are located on our website, www.sourceaudio.net.
01 : Select and edit a preset
By stepping on the SELECT pedal you can select one of four user presets. Edit
a preset by changing values for FREQUENCY , EFFECT or MOTION . Any time that
you change the knob positions of a given preset, that LED will blink slowly to
indicate that the preset is being edited.
02 : Press and hold the SAVE button for two seconds
The LED will blink rapidly to signal that the saving process has begun. When
the light becomes solid, the save process is complete. Note that this process
will over-write any setting that we previously stored in this location.
ADVANCED USER NOTE
It is possible to save different calibration settings for each preset. The procedure is described in the
CALIBRATE section on page 10.
