Modulation Sources

The effects may be swept (or modulated) from any of a variety of control sig-
nals. The

MOD SOURCE

knob does the selection, and the amount of modulation

is set by the

DEPTH

control.

Hot Hand

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 effect sweep following the posi-
tion of your arm. When the

INVERT

light is on, the opposite will be true and the

same gesture will sweep the effect in the opposite direction. 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, dramatic
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/SPEED

knob to control how

quickly an effect will respond to your hand motion. In the most sensitive posi-
tion

(PICK)

the Hot Hand will detect even the slightest motion of the picking

hand. In the

STRUM

position, the Hot Hand will react more slowly. Try strum-

ming some chords normally and listen to how the Hot Hand reacts.
