User Manual

– CONNECTIONS –

INPUT Jack – This ¼” jack is the audio input of the LESTER G. The input

impedance is 1MΩ.

MONO/L and R OUTPUT Jacks – The LESTER G has true stereo output. The

two ¼” output jacks are labeled MONO/L and R. Connect these jacks to two

separate amps or inputs on a mixing board. If using the LESTER G as a mono

effect, we suggest you use the MONO/L output. The output impedance of each

jack is 220Ω.

EXP Jack – Plug an expression pedal into this jack to control the LESTER G’s

rotation speed. See “Using an Expression Pedal” on the next page for more

information on how to use the expression pedal.

The EXP input jack accepts a TRS expression pedal connector or a Tip-Sleeve 0-

5V control voltage input. The expression pedal should ideally use a 10k

potentiometer with linear taper. It must have the wiper connected to TIP and

toe-down connected to RING. Some manufacturers’ pedals do not conform to

this convention and require a special cable/adaptor to swap RING and TIP.

Suggested Expression Pedals: EHX Expression Pedal, M-Audio® EX-P, Moog®

EP-2 & EP-3, Roland® EV-5 or Boss® FV-500L.

9V Power Jack – Plug the output of the LESTER G’s supplied EHX9.6DC 200mA

AC Adapter into the 9V power jack located at the top of the LESTER G. The

LESTER G requires 100mA at 9VDC with a center-negative plug.

– OPERATION AND DESCRIPTION OF MODES –

The LESTER G has three principal modes of operation: FAST, SLOW, and BRAKE,

which simulate the three rotation speeds of a classic rotary speaker cabinet. In

normal operation, quickly 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’s rotation can be adjusted between 1.55Hz

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-

frequency horn oscillates at 0.8Hz, and the low-frequency rotor oscillates at

0.7Hz. Using the SLOW knob, the horn’s rotation can be adjusted between 0.1Hz

and 3.2Hz, and the rotor can be adjusted between 0.0875and 2.8Hz.

BRAKE mode – To enter BRAKE mode, press and hold the SPEED/BRAKE

footswitch for at least half a second, then release it. The LESTER G will gradually

decelerate to a stop, and the bypass LED will hold steady at one color. Once in

BRAKE mode, tap the SPEED/BRAKE footswitch to return to either FAST or SLOW

mode. The LESTER G will return to whichever mode you were in before entering

BRAKE mode.
