If ENVELOPE has been selected as the MOD SOURCE, the MOTION/SPEED

knob sets how fast the envelope signal rises and falls in response to the

guitar input signal. Counterclockwise is faster, and clockwise is slower. The

INVERT switch ﬂips over the direction of modulation sweep by the envelope.

If the LFO has been selected as the MOD SOURCE, the MOTION/SPEED knob

becomes the rate control for the

LFO. Faster rates are in the counterclockwise

direction. (Note that regardless of the speciﬁc modulation source selected,

things happen faster with the

MOTION/SPEED knob set toward the counter-

clockwise direction.) The range of the

LFO is from .2 Hz to 10 Hz (or a period

of ﬁve seconds down to one-tenth of a second.)

If an expression pedal is plugged in to the

EXPRESSION In jack, it will modify

the LFO speed as set by the MOTION/SPEED control. When the pedal is in the

full down position, all

LFO rates are divided by a factor of 2.88, while a full up

position multiplies all rates by

2.88. (Use of an expression pedal thus increas-

es the range of

LFO speeds.) The fastest speeds can produce something of

a ring modulated sound.

There is a Back Page parameter that may be set to permit use of the Hot

Hand for controlling the

LFO speed, instead of the pedal. This may be of

marginal utility if the sensor ring is worn on the picking hand, but nice results

can be obtained with the ring worn on the player’s head or on the guitar body.

The INVERT switch turns the LFO into a “preset” sequencer. A variety of pat-

terns, of different lengths, are pre-stored. The Back Page parameters may

be used to choose the pattern and length. Also available is the transition time

from one step to another. Finally, instead of a repeating sequence of levels,

a random value may be chosen each time the level changes.

When using the sequencer, there is one step per

LFO period. The slowest LFO

rates for normal

LFO mode become too slow to be useful with the sequencer,

and so the slowest

LFO speed has been increased to 1 Hz, while the fastest

rate remains the same at

10 Hz. Control by an expression pedal is still by the

same factors.

MOTION/SPEED Knob/INVERT

If Hot Hand has been selected as the MOD SOURCE, the MOTION/SPEED knob

essentially determines how sensitive the Hot Hand is to rapid motion of

the sensor. Setting this knob towards “Pick” will make the Hot Hand more

sensitive so that even the quickest motions will be picked up. Setting it to

near “Strum” is best for strumming, and “Flail” will reduce the sensitivity so

that only more dramatic (slower) motions will produce a noticeable effect.

Alternatively, the motion knob can be thought of as setting the amount of

“smoothing” of the Hot Hand signal. “Pick” having the least smoothing, while

“Flail” has the most.

The “Pick” position will pass more of the very rapid transient motion caused

by the jar of hitting a string with a pick to go into the ﬁnal control signal. It

can produce something like an envelope follower type of sound. As the knob

is rotated clockwise, less of these quick transients are passed, and things

seem less jittery. You really have to do some experimenting with this control

in order to get a feel for how to adjust it to match your playing style and the

sound you are trying to get.

Turning the

MOTION/SPEED knob all the way around past the six o’clock posi-

tion causes the Hot Hand to invert its axis—up is down and down is up. When

the INVERT light is off, the product is in normal mode, while on indicates

inversion. For the Phaser, with normal mode, the hand up position moves

the frequency response notches to higher frequencies, and with invert moves

them to lower frequencies. For the Flanger, normal mode and hand up posi

tion generally makes the delay lines longer, and thus increases the number

of frequency response notches present.
