VOL Knob Controls the output volume of the LESTER K. As the VOL knob is –
turned clockwise, the output volume increases.
BYPASS Footswitch – This silent footswitch selects whether the LESTER K is in
buffered bypass mode or effect mode.
SPEED/BRAKE footswitch This silent footswitch selects the speed mode of –
the LESTER K. Tap the SPEED/BRAKE footswitch to switch between FAST and
SLOW modes. Press and hold the SPEED/BRAKE footswitch for at least half a
second to enter BRAKE mode. See on the “Operation and Description of Modes”
next page for more information on the speed modes of the LESTER K.
LED When the LESTER K is in effect mode, this LED is lit. The LED pulses –
between green and orange at the speed of the low frequency rotor oscillation.
MONO/L and R INPUT Jacks The LESTER K can be used with either mono –
or stereo inputs. The input jacks are labeled MONO/L and R. When using the
LESTER K with only one input, we suggest you use the MONO/L input. The input
impedance presented at each input jack is 2M .
MONO/L and R OUTPUT Jacks – The LESTER K has true stereo output. The
output jacks are labeled MONO/L and R. If using the LESTER K as a mono effect,
we suggest you use the MONO/L input and output. The LESTER K can also be
used with mono input and stereo output: plug your input into the MONO/L jack
and then connect the MONO/L and R Outputs to two separate amps or inputs on
a mixing board. The output impedance of each output jack is 6 . 80

– – OPERATION AND DESCRIPTION OF MODES
The LESTER K has three modes of operation: FAST, SLOW, and BRAKE, which
simulate the three rotation speeds of a classic rotary speaker cabinet. In normal
operation, tap the SPEED/BRAKE footswitch to switch between FAST and SLOW
modes. Set the FAST and SLOW mode oscillation speeds with the FAST and
SLOW knobs. The oscillation will accelerate or decelerate to the new mode, and
the LED will pulse to indicate the oscillation speed of the low-frequency rotor.
FAST mode FAST mode oscillates at the fast speed of a rotary speaker unit –
for a tremolo-like effect. With the FAST knob at the center position, the high-
frequency horn oscillates at 6.2Hz, and the low-frequency rotor oscillates at
5.9Hz. Using the FAST knob, the horn can be adjusted between 1.55Hz ’s rotation
and 24.8Hz and the rotor can be adjusted between 1.475Hz and 23.6Hz.
SLOW mode SLOW mode oscillates at the slow speed of a rotary speaker unit –
for a chorale-type effect. With the SLOW knob at the center position, the high-
