LFO

Phasers and ﬂangers are typically controlled by an automatically slowly vary-

ing signal called a Low Frequency Oscillator

(LFO). An LFO may be selected as

the modulation source. In addition to the

MOTION/SPEED knob, the speed may

be controlled by an external expression pedal, or by the Hot Hand. The

LFO

produces a sine wave to modulate the Flanger, and a triangle wave for the

Phaser. The

LFO may also be switched to become an audio frequency oscilla-

tor. It can provide ring-modulated sorts of sounds. This option is only for the

seriously crazed.

Sequencer

A sequencer is a device, more commonly associated with synthesizers, that

puts out a repeating series of control levels. While not often found on phasers

and ﬂangers, it is quite an interesting sound. The

LFO may be switched into

driving such a sequencer, by turning on the

INVERT switch from the MOTION/

SPEED knob. 9 different sequence lengths are available, and for each of these

lengths there are

9 different prestored patterns that may be chosen.

A transition time may be set that determines how rapidly the control

signal moves from one level to the next when the sequencer moves on to

the next step.

Instead of putting out a repeating series of levels, the sequencer may be

switched into chosing a random value each time the next step is taken.

See page 31 for a full description of the sequencer control parameters.

Envelope follower

An envelope follower takes the incoming guitar signal and generates a con-

trol signal which gets larger for louder guitar signals. This control signal may

be used as a modulation source.

The attack rate, or the time it takes for the control signal to rise up after a

new note has been struck, may be adjusted. Stacato playing, with a very brief

period of silence between notes, will give the most dramatic results, by allow

ing the control signal to be reset back to zero during the silence.

Calibration (optional)

Your use of Hot Hand will beneﬁt from the unit being calibrated to your play-

ing position and style. In effect, you are telling the control box where your

hand is when it is centered over the strings. Calibration is recommended

when using for the ﬁrst time or when your playing position changes due to

guitar strap changes or when moving from standing to sitting. If you do not

calibrate, the “zero” or center point of the Hot Hand signal may not match the

natural resting position of your hand.

To calibrate, turn the

EFFECT knob to the CALIBRATE position and hold your

strumming hand in its normal playing position over the strings. Then, tap the

ON/OFF pedal once. The

ON/OFF LED will blink for a few seconds. When the

LED is off, you are calibrated and ready to go. Please note that the effect will

be muted when the selector is in the

CALIBRATE position.

Calibration data is remembered until another calibration is performed, even

when the unit is turned off.

ADVANCED USER NOTES

1) The calibration “zero” point does not necessarily need to be in the middle of your arm stroke.

By setting the zero point higher or lower it is possible to span a different range of the effect.

Also, calibration may be required if the Hot Hand sensor is mounted to some other part of your

body (head, foot, etc.)

2) One calibration setting is typically used across all presets. However, it may desirable to create

a different calibration setting for each preset. When the function selector is turned to CALIBRATE

all the preset LEDs will be lit, indicating that you will be recalibrating all the presets. If, before de

pressing the ON/OFF pedal, one hits the SELECT pedal, the light from the last preset selected turns

on. If only one preset LED is lit, then only that preset gets the new calibration data. The remaining

presets are unaffected, even if the last calibration applied to all presets. Pressing SELECT again

toggles back to selecting all presets.

Expression input

If a modulation control signal is needed that is more appropriately generated

by a controller like a wah pedal, an external expression pedal may be plugged

into the

EXPRESSION IN jack.
